您好，我想询问关于DCC1645C这个型号的相机，我们能否使用matlab对该型号的相机进行启动进而采集数据，因为我在尝试使用官网下载的matlab示例启动该型号的相机，发现无法识别该相机

Hello, We have a DCC3240M camera and are using LabView to capture and save intensity fluctuation of fluorescence using the uc480.net files.Can u give me a/some LabView examples, thanks!

お世話になります。 島津製作所の倉本と申します。 御社のDCC1240Cについて質問があります。 本カメラで顕微鏡と組みあわせてウエハの検査を行おうとしております。 LabVIEWを使用しており，サンプルプログラムを参考にしながら実施させて頂いておりますが， 取り込む量が明るすぎて，うまく写真がとれません。 露光量，fps等のサンプルプログラムはあるのですが，ゲイン等の調光調整のサンプルプログラムはありますでしょうか。

Hello, We have a DCC1545M camera and are using LabView to capture and save videos using the uc480.net files. We are able to acquire and save single images, however, acquiring and saving videos doesn't not seem to be working with the video class. Are there any documentation or examples on video acquisition for LabView?

Dear Thorlabs Team, We like to connect multiple DCC cameras to a PC. We noticed that some PC can handle more than three cameras while some PC has already problem opening a second camera. Could you please tell me requirements for PCs (memory, video card, OS) to work with many cameras? Thank you very much,

Dear Sir or Madam, could you please advise where to find following file? uc480CaptureInterface.h The DCx_DirectShow_ProgInterface.pdf has reference on it but it is no "uc480CaptureInterface.h" in DCx_Camera_Interfaces_2018_09.zip So, where to find it? Best regards! Grigory Gelikonov

Dear Thorlabs Team, It is very surprising for me that you do not have any software (drivers) for the Mac OS X operating system. Now I have to figure out how to make it to work. Best regards, Marcin

Hi, I am controlling your camera through Labview. I would like to set a control variable for changing the Gamma function, but the property node Gamma does not show any "Set" options. Can you provide informaion or, better, a vi example showing how to address this problem?.

Hi, We have purchased your camera and would like to use your SDK to develop a C++ application for Fedora22. Unfortunately, it looks like the SDK is only compatible with Ubuntu Linux 16.04 (GLIBC 3.4.22). Can you provide source code for your SDK or provide us an SDK that’s compatible with Fedora22 ?

What is the spectral sensitivity of this camera? Ophir give the spectral range of their NIR camera up front but is coy about the price. You post your prices but make it impossible to find basic technical information about the camera. If you're going to advertise an NIR camera, the first thing anybody is going to want to see is the spectral response curve without wasting a half hour trying to find the information in an endless multi-camera reference manual!!

I have the camera DCC1545M and I have to fit together to the objective MVL6WA. I have used an adapter CS mount to C mount, however if I screw completely the objective to the camera I can`t get to focus the image. I have to unscrew some rounds to get a focused image. Does it need any special adapter or ring to use?. Other question: I have to use also a filter FEL0750, but if I use a SM1QP coupled to the objective the image appears limited by the own lens tube filter holder. Does it is possible to place the filter between the camera and the objective, using some additional piece?. Thank you

Is the flux/signal curve available for DCC1545M? How is it effected by Gain=0 vs Gain=1?

Hello, do your USB cameras support the USB Video Class (UVC) standard? I have a driver written for UVC cameras using the standard and I am looking for strong cameras to use it with.

Hello, when I used CMOS to shoot the plasma generation, I used a filter. The CMOS model is DCC3240M. CMOS has two horizontal and vertical lines. It cannot be eliminated. I suspect it is a bad line. I would like to ask why it is generated. Can you contact me? I can send the picture to your email

Dear Thorlabs, I used to download a driver named 'uc480 Version 4.20 for compact USB cameras' . Where can I find the driver now?

Dear Thorlabs, In our lab we have a Thorlabs camera marked with the identification numbers: UI-3240CP-NIR-GL-TL. We are attempting studies in which we need to know the relative intensity of light of different wavelengths (~700-900nm), to do so I need as much information as possible on the quantum efficiency of this camera in that range. When I attempted to search for UI-3240-NIR-GL-TL I was redirected to the DCC3240N. Are these two products the same or comparable? If not do you have information for the UI-3240-NIR-GL-TL? In particular I see that there is a quantum efficiency curve for the DCC3240-NIR camera. is that curve accurate for the UI-3240 camera? If so can you provide me with the data used to produce that curve (preferably in ASCII format)? if that curve is not accurate for the UI-3240 can you provide me with similar accurate data for that camera. Thank you for your time and help

Dear Thorlabs, Is it possible to select a one or two-line ROI in DCC1645C in order to perform line scan? How many lines per second could I obtain this way?

Is it possible to use the DCC3240N camera with DIC to visualize neurons (and have a good contrast) in brain slice for electrophysiology?

We recently purchased the DCC3240N camera and are using the Thorcam software, including the LabView (LV) drivers. There are several useful LV examples for single frame capture, and a lot of code for video capture built into the uc480.net libraries. But I have not found a LV example for video capture and storage. Would have an example LabView program that saves a video directly to disk?

I'd like to stream and record in video format from the DCC1545M - it is optically monitoring the progress of a experiment. We watch and alter the experimental environment during the run and review and check what happened and when by viewing the recording after the experiment. The ThorCam app seems to allow tiff recording but not avi etc. suggestions?

It seems the image acquisition toolkit of Matlab did not recognize our last Thorlabs camera nor any others we have from Thorlabs. Could you help us a bit ? it is mention on thorlabs it is possible to use these camera on Matlab all the best matthieu

According to the spec table, the frame rate of DCC3260 doesn't increase with reduced ROI, is it true?

Suggest me a lens for DCC1645C, what information need?????

Hello, there is any manual to use the DCC1545M with matlab and the loadlibrary/calllib functions? Best regards

Hello. I want to use DCC1545M with ImageJ. How can I set up camera with ImageJ. Please, give manual or instruction. thanks.

Dear Customer support, could you give a quick note about the major differences between the DCC1545M and the DCC1240M? Many thank in advance, Martin Silies

The software is running on my windows 10 computer, but I can't seem to get an image. Every time I take a snapshot or video I just get a blank image. Can I get some help? What should I do?

Hi, I am looking for a CMOS based camera which i can interface with ARM processor or Microcontroller. Does any of these camera can be interfaced with microcontrollers and where to get those details? Thank you.

Hi I am looking for a compact CMOS camera for fluorescence microscopy applications. I need rolling shutter and between 60-100 fps in a 6mm x 6mm area. I want to synchronize the rolling shutter with a digital pulse in order to have access to individual pixel lines. I am pretty interested in DCC3240M or DCC3260M, the higher the dynamic range, the better. But the problem is that I want a board camera... is there any possibility to buy this cameras, only the board? I need to integrate it inside a system. Thank you in advance, -- Raúl Bola

estimated technical support. I bought a DCC1645c camera and I tried to do a program in Labview 32bit but when loading the sample programs that the program brings when I install it has a problem with the .dll, besides my port does not recognize the camera as USB but when opening the program that brings by default if it recognizes it and lets me see image. How could I make my face recognize labbit 32bit and my COM port to treat it as USB ?. I wait for your response. Thank.

Dear technical support, Is it possible to remove protective filter (glass) from camera DCC3240N? I suspect it might distort the resulting image. Is it possible to unscrew it with 8-point screwdriver or is it necessary to disassemble casing of the camera? -- Best regards, Vlad Gonta

Hi, is there way to get a Zemax file for camera lens?? thanks.

Can I install 4 of DCC3240N cameras in one computer and control them at the same time? I'd like to take 4 images at once. Is it possible to achieve that? Thanks! ---Zhixue

I have DCC3260M. I have several questions regarding the uc480.Messaging command: 1. The .Net manual says one can refer to uc480.NET C# SimpleLive for demo, but I do not find the uc480.Messaging command in this demo. Also, there are multiple files included in SimpleLive. Which file should I look at? Which line should I look at? 2. I do not find uc480MultipleCameraScan in the Scientific Imaging folder. 3. Can you give me an example of how to use this command in Matlab? What should be in the second argument of cam.Messaging.Enable()? Should it be a Matlab listener? What I want to do is to have camera parameters set up in advance, and have the camera wait. When the trigger occurs, I want the camera copies the image of the passed image memory to an array automatically.

Hi, what's the saturation power density for the DCC1545M? I see that the dynamic range is 68.2 dB and the minimum optical power is 2nW/mm2 so I calculate the saturation power density as 514 uW/cm2. Does this sound right?

I am not able to install the software on a new PC (Windows 10, 64-bit). It "rolls back" during the registration part of the install. This program has worked fine on a previous Win10 machine. Your help is greatly appreciated.

Hi, could you let me know how to set the hardware gain with the Matlab support. The 'get','set', syntax doesn't work for the Camera.Gain.Hardware.Scaled property -- the way it works for exposure, pixel clock etc,

Hi, I am hoping to get the raw data from recording video of DCC1645 using uc480 viewer software. Is there any method to get it without compression as AVI format? Thank you so much! Steve

Hi, I'm wondering if there is a way to get hold of example VI's that can be opened in tabview 2010? Many thanks, Tom.

Will the DCC 1545M work at 303 nm? What is the sensitivity?

Dear Sir/Madam I would like to access dcc1545m camera in my 32 bit application that runs under 64 bit windows 10. However Your software does not allow me to install 32 drivers for the camera on 64 bit windows. Is there a way to install those drivers? Thank You

Could you tell me if both DCC3260M and DCC3240N have installed an IR shortpass filter inside the cameras? I will use these two cameras to visualize the light emission around 800 nm. Thanks.

Have been using this camera for years without any problem. Today my computer will have bluescreen once I tried to 'start capture' using the software. The connection is good. My computer runs windows 7 and the error code of blue screen is 0x000000B8.

We would like to use the DCC3260 to capture Flourescent DNA-Bands on Agarose Gels and need to quantify the data. We therefore need output in non-compressed format (like Tif) of the full 12 bit range. Is this possible with the software included? Also is there a way to show saturated pixels in the live view? Thanks Frank

I have an issue with the installation of the device. It's listed as uc480boot and reports code 10 (device did not start) or sometimes code 29 (did not give it the required resources). I've tried installing and reinstalling the ThorCam v2.9 software, as well removing the (hidden) drivers via devmgmt and manually from system32 and system32/drivers. What is the recommended way of making sure I'm uninstalling and installing correctly? Thanks.

We would like to capture raw data from DCC3240N camera. It looks imposible using the ThorCam software (only jpeg format is proposed). So we look at the Matlab script you proposed. We try to change the line corresponding to color format setting with this one: cam.PixelFormat.Set(uc480.Defines.ColorMode.SensorRaw12) But the data collected and casted to uint8 (usign uint8(tmp)) are all equal to 0. We tried other raw format (raw8 and raw16), but same results. We only get valid data when using RGBA8Packed color mode. And if raw data (10 or 12 bits) are returned how the bits are packed in bytes? Could you help us?

I am using the camera with labview to capture images at low light levels. When used in Thorcam the image can be seen quite clearly but when taken with labview the image is much much darker. This change is barely effected by exposure time and even at the same settings captures a drastically different image

I am currently trying to use the DCC3240N within LabVIEW through the latest DOT NET llb, I currently have two main issues. Firstly the format of the CopyToArray function which returns int32[]& s32Image is strange: two 32bit integers for each 10bit pixel value, instead of say a 16bit int per pixel value, are there plans for a better CopyToArray function? Secondly is there an example where the camera is running at 60fps (1280*1024) and copying all data to the PC? The best I have managed is around 30fps.

Hi I've a 1240C but I don't seem to be able to get the white balance to be much good. I have to have about 69x gain on the blue and 1 on the red to get close (using thorcam software). I want to use micromanager but all the pictures come out red (with my eyes the image is white). Do you have any advice on this. Best

Can I get sensitivity data for the DCC1545M and DCC1645C out to 330 nm? Thanks.

DCC3260M is a 12bit monochrome camera not compatible with ThorCam version in the CD coming with the camera. The latest version of ThorCam 2.9 downloaded also results in an error in making a list of cameras. Pseudocolor view is not compatible with DCC3260M, while it works fine in grayscale mode. ThorCam needs to be updated to be compatible with 12bit cameras. It is only fully compatible with 8bit camera so far.

Hi there! I've got a DCC1240C CMOS camera as part of my modular optical tweezers setup I ordered from you (OTKB/M). The image on my camera, however, shows the presence of a lot of noise that obstructs the clear view of my sample. I have followed all the steps listed in the manual for connecting the camera and installing the software, but I seem to be struggling with adjusting the right settings. Would you please advise on what settings would one normally use to properly image 1.5-micron silica particles with OI 100x objective?

We are trying to use DCC1545M using LaBview but it is asking for a library which is not include in the SW download. We are wondering if the library is avaliable somewhere. Thanks

I need access to the full 10bit raw data of the DCC3240NIR sensor. I have been running C# software to achieve this with DCC1240M, but cannot see how to do this with 10bit mode. If I set pixelfmt to mono10 I can display frames - but what format is data in if I attempt to copymem to array? If I copy to an Int32 array, does each element respresent the 10bit value of a pixel - or is it packed in some way?

MATLAB support!!! Please provide Matlab drivers or support for your cameras. The suggested use of MEX files etc does not work. I know many who would appreciate these drivers. Thanks

I can't install the software to use CMOS (DCC3240M). The company can tell one engineering to fix for me. My address: Mirea 1, 212, College of Bionano Technology,Gachon University, 1342 Seongnam- daero, Sujeong-gu, Seongnam- si, Gyeonggi-do, 461-701, Korea. My phone: 010-6585-5758

We develop our LabView interface (ThorCam 2.6.7064) for our DCC3240N. DCC3240N is 10-bit but the "SetColorMode" function in the SDK allow only 8-bit monochrome, 24 and 32-bit RGB. How do we set the camera to 10-bit in LabView?

We have 3 or 4 of these cameras but have always just used ThorCam. We want to do more custom operations now, so I've been trying to develop our own c++ application with image acquisition using this camera. Unfortunately, it's been quite frustrating. All I really need is a matrix whose values get updated every time a new image is acquired. An example that sounds useful is "uc480PixelPeek" but I haven't been able locate it. Also, it would be great if this camera could integrate with opencv image acquisition function.

I am research engineer of Korea Photonics Technology Institute, Korea. During my development, I need a camera which has sensitivity range of 200~380nm. Would you introduce for me candidates available for optical microscope. Best regards, Yoon Seok Kim

I'm using this camera from matlab 2016a using the .NET SDK. Everything works, but when exiting the camera using Camera.Exit() is leaves the camera 'In Use' as seen by uc480.Info.Camera.GetCameraList and a new object cannot be created unless matlab is closed and restarted. How can I use the .NET SDK to release the camera so that it is no longer in use?

I have a DCC1645C camera, and it works very well. Thanks! The only problem is the colors in the Thorcam software are very hard to see through my laser safety glasses. In a future version of the software, it would be helpful to have the ability to change the colors to select colors that work with laser safety glasses. The green color in histograms and horizontal/vertical lines profile plots are especially hard to see.

Hello, I have just received a DCC1240C. The uc480 software allows to perform histogram, vertical line profile or horizontal line profile. Is there any way to save these data?

Hello, I have just received a brand new DCC1545m. I installed the latest TSI drivers and the camera works fine with ThorCam. I need to operate the camera with Matlab R2015b on a Windows 7 Pro 64bits SP1. Windows Device manager detects it as a USB controller. I installed the Thorlabsimaq adaptor, but imaqtool still doesn't detect the camera. Could you please tell me how to fix this and operate the camera with Matlab using MEX files ? Thanks in advance. Thomas

We would like to use one of the USB 2.0 cameras from Linux. We have a kernel 3.13 (or later version). However the notes for the Linux SDK indicate only the old kernels 2.6 are supported. Are newer Linux versions supported with your products? Or is it just a matter of using a newer SDK version directly from IDS?

Hello! I am having trouble selecting an AOI with the Labview SDK and the DCC1545M. Could someone please get back to me? Thanks a bunch, Caroline

Hi there, I've bought a DCC1545M camera which I'd like to control with a 32bit Labview (2012) on a 64bit Win7 operating system. I searched for the .dll mentioned in earlier posts (uc480_LabVIEW.dll) (which I found in C:\Windows\SysWOW64) but in order to import it into LabVIEW I also need a head er file (*.h). I tried out a few random ones from the installation folder but no joy. Could you please get back to me how to install the Labview drivers for your camera? Thanks very much Caroline

Is there some way to use this camera with Linux (Ubuntu)?

Where are the .NET examples. I have downloaded every file available and there are no examples which use the .NET SDK. The documentation for the .NET implementation mentions a .NET example, but I cant find it, and I'm losing my patients. Please respond.

I am attempting to incorporate this camera (DCC1545M) into a test rig I am developing in C#. I have encountered a number of problems in doing this and would like to ask a few questions. Firstly, I have downloaded all the examples, documentation etc that I can find. Using the .NET wrapper (uc480DotNet.dll) and the simple example provided in ITN000563-D03.pdf I have attempted to follow the simple startup instructions to get some kind of image streaming. I need to be able to manipulate the image later on so I need access to the memory where the image is being captured. I can get a list of devices, so far I'm only using 1 but in the future there could be 2 or more cameras to juggle. The problems come in when I attempt to Acquisition.Capture(). I'm Allocating memory, setting it to active, I'm subscribed to the EventFrame and nothing is happening. Ive tried to use Display.Render(m_s32MemID, m_PicBoxHandle, DisplayRenderMode.FitToWindow), but still no luck. I'm also unable to Stop or Exit the camera in order to connect to a second device. I then tried to look at you're C# example and was horrified to see that you guys didn't even bother using the .Net wrapper you have provided and instead resorted to talking directly to the SDK. I can only assume this is because this .Net wrapper is bogus. Should I be going the same route as you're C# example, or is there an example that uses the .net wrapper that works and I can look at? I have now wasted 3 days of my time attempting to use the documentation and I'm getting no where and would really appreciate any advice or guidance you could provide me with. Many thanks in advance for your help.

Hi, I have a similar problem with "an.gong": "I try to use Labview 2014 to control DCC3240M camera. My problem is when I tried to open the examples in your Labview driver folder, it reminded me lacking a file named "uc480_Labview.dll", and I could not find this file even by searching my whole computer." Thanks.

Hi, I am trying to control the DCC1545M camera using the provided C# SDK(uc480DotNet.dll) in vs2012 on Windows 7. I'm getting an exception when I try to use started quickly. I get an error code.

i've purchased DCC1545M and run the streaming-8bit example located at C:\Program Files\Thorlabs\Scientific Imaging\DCx Camera Support\OtherDrivers\LabVIEW\8.x\Examples. but when i run the labview example program , there is a error at sub vi ,capturevideo.vi, with error code number -1. so can i get any imformation about the error code related to ? thank you for your support.

I've purchased DCC1240M and I'm running ThorCam to make a single frame snapshot for acquiring gray-scale images. Now here are my two questions: 1. I've been informed of the Auto White Balance adjustment and Color Saturation adjustment from the Manual. Are they still in use in my application situation? I thought they were only in relationship with the color images, not gray-scale images, but I find the Color Saturation adjustment enable in the "image enhancement" page of ThorCam settings. Actually I don't want the auto adjustment functions because I need the RAW data from read-out of CMOS. 2. When saving images by ThorCam with DCC1240M, the only file format for selection is JPEG format. However, JPEG-compression is a kind of lossy compression. Can I save single frame image with lossless compression format? How? If you could drop me a line I would appreciate it. Thank you for your support.

Hi, I would be interested to use the DCC1645C for colorimetry, after calibration of the R,G,B channels. Could you provide the raw data for the calibration (showed in the sensitivity tab). Also is the A/D unit level linear with the photon fluence? Is it possible to retrieve the RED, Green and Blu image from the software? Thanks

I am trying to control a DCC1545M using labview. The camera shows up and is usable in Ni-Max and the Vision Acquisition Express macro, but as I run it on Labview as a script I get an undefined error. Do you have any ide of what to do?

Hi, I wonder if this is the right place for trouble-shooting. I try to use Labview 2014 to control DCC3240M camera. My problem is when I tried to open the examples in your Labview driver folder, it reminded me lacking a file named "uc480_Labview.dll", and I could not find this file even by searching my whole computer.

Hi, I am trying to control the DCC1545M camera using the provided C++ SDK in Qt on Windows 7. I'm getting an exception when I try to use is_SetColorMode to IS_CM_MONO8 (Even though I have working LabView code that does this ... if I use IS_CM_RGB32 it works ok but does this make sense for a monochrome camera?). I also can't use the is_CaptureVideo or is_FreezeVideo functions -- I get an error code of -1. I'm following the directions in the SDK manual in my code but it's still not working and I'm not getting helpful errors. Please help!

Hallo, I want to use a DCC1645C camera for a vision application and I have the following sample code to test if the camera works: int main() { int key; Mat img; VideoCapture capture(1); namedWindow("mainWin", CV_WINDOW_AUTOSIZE); while(capture.isOpened()) { // make sure we grabbed the frame successfully if (!capture.read(img)) { cout << "No frame" << endl; break; } imshow("mainWin", img); key = waitKey(10); if(key == 27) break; } } I can open the camera but I am not getting any frames (works without problems with my webcam). Do you have any idea what might be wrong? I am using windows 8.1, with eclipse (luna) and opencv. I have both the "ThorlabsDCx_camera_V4.20" and "TSI_Camera_Setup_X64" installed, because with only the "TSI_Camera" I could not even open the camera.

Where is the Tsi_sdk.dll header file?

I have purchased a DCC1645C camera, and want to control it with Lab View, but the labview camera dlls do not find any camera...

I purchased one of these recently expecting the software to be similar to an analogous model I bought from Edmund Optics. While it's mostly similar, thorcam for some reason only offers video as multiframe TIFF instead of avi with jpeg compression (which I am used to from the Edmund software). As both your software and the EO software are presumably built from the same SDK (that I have neither interest in nor time to mess with), is there a version of thorcam that allows saving to any kind of compressed video format? Multipage full-frame tiffs at 30fps are really only good for 10s of seconds at most before they become incredibly big, and this really decreases the utility of the software and thus the camera itself.

I have switched to use DCC3240N with Thorcam V2.2. There is a poor quality jpeg RGB output only while the sensor is a NIR monochrome one. How can I get a BMP or PNG output with a higher quality and in monochrome format (pixel, intensity). You are not providing a Tiff output for this type of camera which is ridiculous. There is no option for false color preview of monochrome images. The output file is only supporting 8 bits which is smaller than the 10 bit contrast of the sensor. All of these options are available in other commercial products...

Useless product!

Dear Thor Labs, I am writing to ask whether the DCC3240 series of cameras has an ASCOM compatible driver available and if not, is your SDK free for use so that someone in the public domain could create one? The WDM compatibility of the camera makes it available to some Astronomy applications, but an ASCOM driver would increase application compatibility considerably. I would be interested in writing such a ASCOM driver using your SDK if nobody has already done so. If you could drop me a line I would appreciate it. Regards, Brett

I'm developing an application in c/c++ on Windows using DCC1545M camera and the corresponding c API. I cannot use newer functions like is_Exposure(...). When I try to use it I receive a message that it was not declared, though I can find it in the header file. I currently use the is_GetExposureRange(...) and other obsolete functions and I would like to change to the new functions. Could you please help me with this? Thank you, Silviu

Owning both the DCC16xx and DCC15xx model and developing a image analysis program for Windows and Linux, I'm quite puzzled about the organization of the drivers. When downloading the Windows setup, I'll get the uc480.h, .lib and .dll for x86 and x64. But under Linux (Ubuntu) those files are named ueye.h and ueye_api.so. According to the content of the headers, these libraries differ. Of course, I can include a differentiation in my program to switch between uc480 and ueye. But it appears to me that the uc480 should be available for Linux systems as well (e.g. to be found in the uc480.h as "DRIVER_DLL_NAME". The manual does also not mention any such (naming) issue. Thanks for your support, Clemens

I am interested in pixel uniformity for DCC1545M. Could you estimate this ?

The labeling of devices in "CCD / CMOS Cameras" would be better labeled as CCD / CMOS Sensors. The devices do not have a lens and therefore can not form an image; ergo, these devices are not cameras! It would be much easier to purchase the sensors if they have a properly labeled product name. Thank you for your consideration in this matter.

We have a DCC1545M that we use as part of a spectrometer setup (collecting light from a grating). However, we find that the noise is quite high (we are looking for wavelenght of the minimum of the spectrum). We use Labview drivers. What would be the best settings to reduce the noise (I think light levels are high enough) Would the linear CCD offer big improvement for this application (would you have a comparison), Many thanks!

I cannot find several of the basic radiometric specs for this device. In particular, Read Noise (e), Well Capacity(e), and Dark Current. There are lots of other specs, but these 3, along with pixel geometry, QE and frame rate, are generally the most critical for figuring out if a camera will do the job! Any data on this? Thanks!

Hello. I am acquiring videos with a DCC1545M, running uc480Viewer on a Windows 7 PC with NTFS and 16 GB of RAM, but the maximal file size is limited to 4096 MB. I can't see how to increase the file size limit. Any ideas? Thanks

Hello, we are using a DCC1545M on our microscope. I am trying to use the setAOI function on LabView to decrease the size of my output images (and I cannot use the bining since I want to keep my resolution as high as possible). However, despite the input Width_IN and Height_IN I am setting, it seems the output AOI will always display a width of 1280 pixels and a height such as Height_OUT*1280 = Width_IN*Height_IN. Just to make things clear, I made sure that all the parameters (X,Y,Width and Height) are divisible by 16. Do you have any suggestions concerning this issue?

We have DC1545M camera and it would be a great feature of the software if it could show in live view mode, the image in different color maps depending on the intensity (similar to beam profilers). I am lacking this feature very much. Another useful feature would be to see in live view mode the 2D surface profile (now there is only horizontal/vertical line profile). If you add these features to the next version of the software, the camera would be very valuable purchase.

I am using the DC1545M and need to acquire line traces with high digitalization depth. Is it possible use the DC1545M in 10bit mode in the viewer software or in the Labview?

Can I have the implementation steps in order to use MEX files to recognize the camera in Matlab? Thank you

Hello, I have a DCC3240M and it works fine with LabView. My question is: is it possible to acquire data in 10bit greyscale ? The provided examples use the ColorMode=RGB24 then i think the result is in 8bit. And i did not fount the option to set the ColorMode to IS_CM_MONO_16 or IS_CM_MONO_12. The LabView driver only permits to choose the following options: RGB32, RGB24 or Y8 Monochrom. I use Windows 7 32b, LabView 2010, and the link is USB3. Best regards, Stephane

To whom it may concern, I have recently received the DCC1545M CMOS Camera. I tried playing around with it a little bit to test its capabilities. However, when I use the uc480 Viewer and try to zoom, the image always zooms to the top right corner. Checking the manual, I noticed that the current cursor position for the zoom and pixelzoom window is not displayed at the bottom right corner of the main screen. What can I do to change this? Also, is it still true, that you don't offer false color capabilities within uc480 viewer? Best regards Till Klostermann

I've seen from previews comments that apparently it is possible to use the Image Acquisition Toolbox from Matlab to capture images. Is it really possible without using mex files? If not, is there a way to force windows to recognize the camera as a camera, not as a USB device (as seen from the Device Manager from Windows)? Thanks in advance! Hilton

Hi there. How do I save images as a .tif format with the uc480Viewer software? Thanks. -Jack

Does the DCC1645C have a linear response (signal linear with brightness)? The manual talks about linear, logarithmic and gamma functions for these cameras but doesn't talk about the camera's settings specifically. Does it have a look-up table that's accessible? thanks

can the camera output in labview a matrix of the image pixel values? It would be nice since we would not have to purchase the labview image processing libraries.

We purchased a DCC1545M. Could you tell me how to save the time stamps along with the vedio when using uc480 Viewer? We also tried using Matlab, but the frame rate did not increase when we use small ROI (stays at around 10 Hz). We need a frame rate of larger than 300Hz. We will appreciate it very much if there is a simple way to make that happen in Matlab. Thank you!

What is the sensitivity of the DCC1545M at 1064 nm?

I recently bought a CMOS 2.0 USB camera DCC1545M and am exploring the options to control it. It seems that MATLAB image acquisition toolbox does have all the functions that I need for my application; however, before I implement my application based on the toolbox I wanted to know if using the toolbox will adversely affect the acquisition speed (frames per second). I am specially concerned about the speed when the region of interest is small. I need a frame per second rate of about 300 for a region of interest of size about 100-by-100 pixels.

How do those cameras behave at 1.06µm? Note that I have as much light as I want.

I'm using this camera in adigital holographic imaging system. However, when recording a short video, the total intensity in the field of view decreases significantly in each frame. I've used two different cameras and two different light sources. Why does it happens and what's the solution?

What is the sensitivity level of these cameras? It does not seem to be listed.

This is a response from Thomas at Thorlabs. Please disconnect the camera and uninstall the software, you can download the newest software version for DCU and DCC Series USB Cameras from our homepage: http://www.thorlabs.com/software_pages/ViewSoftwarePage.cfm?Code=DCx. Please download and install the newest software before connecting camera. After the installation is successfully completed you can connect the camera to the computer. The first time you connect a DCx camera to a USB port under Windows, two driver files will be registered. The first file ('uc480_boot') contains the generic driver, the second file the model-specific driver. The model will be immediately recognized whenever you connect the camera to this port again. If you use a different port, the registration will be repeated. Under Windows the camera will be listed in the uc480 Camera Manager's camera list. When the camera has been correctly installed, the LED on the back of the camera lights up green. I will contact you directly if you need further information. Best Regards, Thomas

Hi,what should I do if I plugged in the camera first before I installed the application software? the computer can not install the driver successfully. It's the CMOS camera. Thanks.

A response from Julien at Thorlabs: Thank you for your inquiry at Thorlabs! The sensor is not linearized for the RGB color channels sich that for colorimetry applications, the responsivity of each channel has to be taken into account. The values can be found on the webpage of the cameras under the tab "responsivity". Please note also that the bandpass filter for the red channel has a quite high transmission in the NIR such that an extra IT filter is used on those cameras.

Hello! I got a DCC1645C camera for colorimetry, reading some literature of the CCD cameras I found that for this purposing, the cameras have to pass over a linealization process, I was wondering if this camera does have a linear relationship between the RGB values vs. the luminance. Do you have some extra information that shows the behavior of linealization or non-linealization of this camera? Thank you so much Natalith

A response from Thomas at Thorlabs: Thank you very much for your request. The C/C++ drivers and examples that we provide can be imported to Matlab by using MEX files. You can also use the acquisition toolbox but the amount of available functions over the camera parameter is limited. I will contact you directly to discuss the details of your application.

To whom it may concern: We recently bought a DCC1545M camera from Thorlabs. It turns out that the image adjusting capabilities of the viewer software are not entirely sufficient for our purposes. We were therefore wondering if you would be able to provide instructions to interface the camera with Matlab? Specifically, we are interested in live acquisition and subsequent display of the images through Matlab after some simple image processing. Thank you in advance, Fabrizio Gabbiani

A response form Julien at Thorlabs: Thank you for your feedback! This issue is most probably related to the fact that the allocated memory in openCV for this camera is too small. The camera will typically deliver an image having the same size as the memory that is allocated for this image. This means taht if this size is too small, the resolution will be automatically reduced. I will contact you directly to see how the declaration of the memory space was made and if this could be the reason for the issue.

Actually I don't understand this issue, when I start camera 1645c with default software uc480 Viewer, it gives full resolution 1280x1024. but when I start using camera with my software using OpenCV, it gives 640x480 resolution. Why is that so, why it is running on small resolution. whats wrong I am doing. I have re-installed the software, did everything that I can do but still it gives low resolution. Kindly if possible then reply me soon with solution. Thanks

A response form Julien at Thorlabs: Thank you for your inquiry! The number of camera that can be used is high (>50). The main practical limitation is usually not the amount of devices the USB protocol can deal with but rather the bandwidth available on the computer or on the USB hubs used. The maximum bandwidth is 480Mb/s which means that if the number of information transiting over the bus is higher than this, the frame rate will have to be lowered. As far as the software is concerned, one instance will need to be opened for each camera used. This limitation of course does not apply when the SDK is used and several cameras can be read out simultaneously.

How many DC1645C can be used on the same computer? How does the software handle this?

A response from Julien at Thorlabs: Thank you for your inquiry. We provide C/C++ drivers and examples that can be imported into Matlab using MEX files. It is in principle also possible to use the image acquisition toolbox but the amount of available controls over the camera parameter is limited.

Hello! Actually I'm interested on the way to work with these cameras and implementing them on matlab, during the last days we adquired at the lab a dcc1645c camera for working on colorimetry; as an important issue, many files that are in articles on colorimetry are in matlab, that's why I would like to get some help with that. thanks!

Response from Jeremy at Thorlabs: We will get in contact with you to discuss ways to implement the cameras into MatLab.

I would also be very interested in implementing using this camera with matlab. (I have purchased four DCC series cameras from Thorlabs and was disappointed when I also couldn't get them to work.) I would be interested in putting together a tutorial on how to integrate them into matlab. Julien, would you please contact me and explain to me what the special mex steps are (as you suggest in your 7-26 response?) Thanks!

Response from Jeremy at Thorlabs: This software does not have the functionality that the Leica camera software provides, as described by you. However,There are settings which can be changed to achieve better contrast. The settings can be found by right clicking on the screen -> "Properties" -> "AES/AGC".

Hi there, I purchased a DCC1545M camera, which works fine. I use the camera in preview mode only, to monitor the events in a microscope setup. I'm wondering if there is a easy way to increase the contrast of the picture. I'm used to the Leica camera software... There you have an histogram of the pictures gray levels, and you can chose two gray values between which your picture information lies, and make these two values the new black and white in your picture. In this way you can e.g. make a 0.3-gray displayed black and a 0.4-gray being displayed white. Correspondingly, the contrast of everything inbetween increases drastically. Is there any easy way of doing something similar? Free third party software? I managed to get a preview from the camera in Matlab. However, if i want to manipulate the image data, I think I have to plot every single frame, and then I end up with roughly 2 frames per second... Any suggestions?

A response from Julien at Thorlabs: Thank you for your feedback! We are sorry about the incovenience that the faulty link creates. I will send you the manual per email directly while we fix the link

Hello, I am reporting a broken link: The User Manual links for the DCC-1645 camera is broken - it goes to a redirect page, which then goes to a "Virtual Directory Listing Denied" page. Thanks, -- Demis

a response from Julien at Thorlabs: Thank you for your inquiry. The most stable way to implement our camera within Matlab is to use MEXX files to be able to use directly the standard dll without going through the winvideo functions. I will contact you directly to discuss the implementation steps.

I am trying to have matlab recognize the camera. We oringally had the 2009 version of matlab and now we have the 2012 version. The camera used to be recognized as 'winvideo' and is no longer recognized and matlab will not recognize the .dll for the camera. Do you know how I can get Matlab to recognize this camera?

A response from Julien at Thorlabs: Thank you for your inquiry! The camera can indeed be controlled using ActiveX controls. This functionnality was originally designed however for implementation within C/C++ or visual basic. the ActiveX controls are based on the dll ad thus require the use of the header file in the code. It will thus be necessary to go through MEX files at some point. This in turn means that it would probably be more efficient to stick to the C++ driver and implement the complete controls in Matlab using MEX files. This approach would probably correspond to the same programming effort but would offer more control possibilities than the activeX approach. I will contact you directly to discuss the possible options.

Dear Madam or Sir, I would like to use my camera with MATLAB through ActiveX. Can I directly access to the image memory by calling any of the existing ActiveX functions? Is there a possibility to read out the image memory in MATLAB?

A response from Julien at Thorlabs: Thank you for your inquiry! the extent to which the hologram will be ok will largely depend on the exact optical system you are using. If the interference pattern when using a BC106-VIS was not satisfactory, it will also not work when using a DCC1240M since the pixel sizes are very similar. further, the DCC1240M uses a protective glass plate inform of the Cmos chip, which could also lead to an extra etalon effect that might add another modulation to the interference pattern. I will contact you directly to discuss the details of your setup in order to see what can be expected.

Can I use DCC1240M to record interference pattern of a hologram illuminated by He:Ne laser? I tried beam profiler for that but the picture was very deformed.

A response form Julien at Thorlabs: I am sorry for the inconvenience the experienced problem must have created. I think that the issue you are having is related to the fact that windows XP saves the driver for each single user profile separately unless the option "install for all users" has been selected during the installation. I will contact you directly to help troubleshooting this issue.

we have installed DCx software for using DCC1645C using Administrator account on Windows XP PC. However, when trying to run software on non-admin accounts, get a message that installation file not available and does not load/install. Can you offer any advice?

A resposne form Julien at Thorlabs: Thank you for your inquiry! We can in principle offer only the chip and the main PCB for this camera. The main and only problem while using a version without housing is of course that the protection offered by the housing is gone such that critical components are more exposed to mechanical damages. I will contact directly you to send you a quote for the camera with and without housing.

We're interested in the DCC1545M - but just the board+sensor itself, not the housing (we're an OEM and have major space constraints). Would this be possible? Or perhaps can we just get it and remove its housing manually, assuming it can be opened easily? Thanks.

A response from Julien at Thorlabs: thank you for your inquiry. The minimum exposure time in trigger mode is specified as 9ms.

Hi, What is the minimum exposure time when taking images by asynchronous triggering for DC1240M? Thanks.

A response from Julien at Thorlabs: Thank you for contacting us on this matter. The installation of such a camera should actually be very straightforward. The behavior you describe is not normal and indicates that the camera you have is faulty. I also find it very surprising that two cameras failed within such a short time. Those cameras are normally very reliable and sturdy. I will contact you in order to see if a root cause for the repeated problem can be found and set up the repair of the camera.

I have a DCC1645C camera that no longer seems to work. I plugged it into a 64-bit Windows 7 machine, which recognized the device and installed the appropriate drivers. The camera worked as expected for ~15 minutes, but then it stopped. I unplugged and plugged it back in, but when I ran the UC480 viewer software I received an error saying that no UC480 camera was present. I uninstalled and reinstalled the software to no avail. Moreover, if I look at Device Manager, nothing appears when I plug in the camera under the Universal Serial Bus controllers section. I had this problem with an identical camera around 6 months ago, but had figured the particular camera was bad. Now I'm suspicious something else is happening since this happened to a second camera. I also tried several USB cables as well as several Windows 7 64 bit machines (and one Windows XP 32-bit machine) and the UC480 viewer software still reported a camera as not present.

A response from Julien at Thorlabs: Thank you for your feedback. The problems you describe are highly unusual. We would be happy to send you a replacement objective that should solve both problems. I will contact you directly to discuss the way we can ship you this part.

Hi, I've just received a DCC1545M camera with a MVL25M23 lens. I just wanted to mention that the CS-to-C mount adapater provided with the camera lacks ~0.4 mm of internal diameter to let the lens pass through. Otherwise, the lens is stuck in the "NEAR" focusing position. This was fixed in 10 minutes at my university, but can be a pain if you don't have the correct tools.

A response from Julien at Thorlabs: thank you for your question. It is possible to connect two cameras simultaneously to a computer. in order to view the images from those two cameras, two instances of the program will need to run. The cameras use a USB 2.0 communication protocol so please note that depending on the resolution chosen, high frame rates might not be achievable because of the USB bandwidth limitation if the cameras are used on the same root hub.

Hi there, can I connect two cameras to a computer and view images from both cameras simultaneously within the image viewer, or running two instances of the image viewer? Thanks

A response for Julien at Thorlabs: Thank you for your inquiry! The DCC cameras are unfortunately not supported by AMCap so that the only way to access them through matlab will consist in importing the drivers for this. This can be achieved by creating the appropriate MEX files so as to be able to use directly the C++ drivers for the camera.

Hi, I've got a similar question to ding's on 2012-01-31: I'm using a DCC1545M, works great with the UC480 viewer (on Win 7 pro). But it isn't recognized by AMCap or by Image Acquisition Toolbox. I need to acquire video from Matlab, any advice on how to get the camera recognized would be appreciated. I've got the latest driver download from Thorlabs, have reinstalled, etc. Thanks in advance.

A response from Julien at Thorlabs: The fact that the camera is not recongnized as such by the computer could either imply that the driver was only partially installed or that there is an issue with the camera interfact hardware. I will ocntact you directly to further troubleshoot and find out where the problem is.

Hi, I got Dcc16545c. I installed the drive. I checked the device manager, I only saw it listed as a universal serial bus controllers. How can I change it make it list in imaging devices?? (since it is not shown in the the 'imaging devices', matlab cannot use the dcc1645c) Thanks.

Response from Buki at Thorlabs: Unfortunately we do not currently offer lenses that would give you a magnification of 35X . We will consider your request as we continue to expand our product line. We have contacted you with more information but please email TechSupport@thorlabs.com if you have further questions.

Hi Service, I got your DCC1645C camera. Please recommend a lens for that camera there will give me ~ 35 times magnification and a working distance of ~ 70 mm. Anything close to those numbers will work for me. Thanks, Karl

A response from Tyler at Thorlabs: The DCC1515 uses a Micron MT9M001 sensor. The quantum efficiency of that sensor is slightly less than than 5% at 976 nm according to the plot on the manufactures specification sheet. This document is available by clicking on the small red document icon for the part located in the price box. We will also contact you via email with this information.

Can I know the quantum efficiency of DCC1545M at 976 nm?

Response from Buki at Thorlabs.com Thank you for your feedback. The thread is 1.00"-32 and this information is provided in the "Overview" tab and also shown as “CS mount” in the AutoCAD drawing. The adapters are included with the camera and we have a diagram in the "Overview" tab that shows how to put the items together. Please contact TechSupport@thorlabs.com to further discuss your application.

DCC1645C the drawing doesn't detail what threads are used, also not in the general description. Additionally it would be nice to know how to adapt this camera to a cage plate or SM1 thread as shown for the other camera group on this page.

A response from Julien at Thorlabs: this problem was related to a driver issue in the version you are currently using. this has however been fixed in the most recent version that can be downloaded from the software page of the DCC1645C camera.

Hi. I have a USB CMOS camera DCC1645C. I dont have problems to use it with the software uc480 viewer, but Windows 7 64 bits doesn't recognize it as a camera, instead is shown like a not specified device. the driver version is 3.50.9.0 with date 12-11-2009. I download the driver from this site. there is a new version of the driver?

A response form Julien at Thorlabs: yes this is possible. One only needs to open two instances of the sowftare and connect each of those instances to one of the cameras.

Can the software get images from 2 CMOS and show them at the same time?

Response from Javier at Thorlabs to paul.s.hamilton: We introduced our DCC CMOS cameras with low cost in mind. Making the external hardware trigger interface available requires a redesign of housing of the camera, plus a few other changes that would drive cost up. Regarding your second question about the flash and long term exposure, these features are available only if the camera has a hardware interface for trigger and flash, as our CCD DCU series cameras do. The flash is controlled via a kind of "trigger out" port, and long term exposure is possible only with external triggering. So it is not only a question of the software not supporting this, but the hardware does not allow for this feature, either. I will contact you directly for further support.

With a little tinkering, I just found out that these CMOS cameras are in fact externally triggerable. In the manual, you see the PC board inside has a spot for a 9-pin connector which has pins for triggering (as well as 2 strobes, power, and most likely the USB signals). Thorlabs (or your supplier), why dont you make this feature available to us without having to hack it ourselves? The cameras are infinitely more useful with the external triggering....Along these lines, I was wondering if there are any experts on the software that can tell me if the flash or long-term exposure features can be used with the DCCs. The uc480 viewer software doesnt allow it but the spec sheet for the CMOS chip suggests it should be possible.

Response from Javier at Thorlabs to enrique.balleza: Thank you very much for contacting us. We currently do not have provide a direct driver for controlling our CCD and CMOS cameras with MicroManager.

Hi, I bought this camera to use it with micro-manager through the TWAIN camera adapter. However, micromanager doesnt recognize the camera. Do you have any suggestions? Thank you, Enrique

Response from Javier at Thorlabs to jun: Thank you very much for contacting us, and we sincerely apologize about not getting back to you sooner. Unfortunately, the DCC1545M will most likely not be suitable for your application, as the quantum efficiency of the CMOS chip at 1050 nm is very low, around 2%. I will contact you directly to determine a suitable alternative for your application. Perhaps we can recommend a Silicon or Germanium based detector, or a beam profiler.

last week I sent email to ask about this cmos camera.But so far I have not recieved any reply. So I sent my question here. I am interested in this DCC1545M cmos camera. But I am not sure if it suitalbe for our laser which has wavelength of 1053nm, repetition rate of 10Hz.If it is works for our laser, please send me a quote. Thanks. Jun Zhang

Response from Javier at Thorlabs to haig.norian: Thank you very much for contacting us. It looks like the USB drivers of the camera need to be updated. You can check the Device Manager to make sure that the USB component is connected, and if so, you should be able to update the drivers. Please contact us at techsupport@thorlabs.com in case this procedure does not work and we will gladly assist you.

Hello, I installed the DC1645C on Windows XP. Worked perfectly for a day. The next day, when I plugged the USB cable into my laptop, Windows would not see any attached USB devices. Error message in UV Viewer = No UC4800 devices found. Ive installed/reinstalled all software. However, I cannot get the laptop to recognize that the USB camera is plugged in. Any help would be greatly appreciated.

A response from Julien at Thorlabs: Thank you for your inquiry! the mechanical aspect should be manageable but I guess the stereotactic photography will require a large programing investment as the software does not include such function by default. I will contact you directly in order to find out which solution would be possible.

Hi! Would it be possible to mount two of these cameras on a frame at about a right angle for stereotactic photography? And can this set-up be made easily portable?

Response from Javier at Thorlabs to Thomas Ruckstuhl: Thank you very much for contacting us. You can certainly operate two cameras simultaneously when using the uc480 Viewer and also when using other software platform such as LabVIEW. The main requirement is that each camera must have its one ID number. Page 31 of the manual (http://www.thorlabs.com/Thorcat/19400/19418-D02.pdf) contains instructions for setting the camera ID.

We need to use 2 cameras in our setup. Is it possible run two DCC1545M simultaneously? Thank you Thomas Ruckstuhl, University of Zurich

Response from Javier at Thorlabs to fg2251: Thank you very much for contacting us with your request. The DCC1645C is not responsive at 800 nm, since it has an IR cut filter, which cannot be easily removed, with a cut-off wavelength of 650 nm. We would recommend using the DCC1545M monochrome CMOS camera instead (see Responsivity tab above). Regarding damage threshold, we currently do not have a concise value; however, as a guideline, we would recommend limiting the input to < 0.5 J/cm^2.

Hi I want to use the color CMOS to monitor the beam (Ti:S fs 800nm and 400nm) spot movement in a delay line. I need to check if delay line is well working. Is the Color cmos sensitive to 800nm? and which is the damage threshold? In Responsivity specs you report a IR filter? What is that? is external optional filter or is a intrinsic cut-off of responsivity? Let me know Felice Gesuele

A response form Julien at Thorlabs: We have as of now no sample code with OpenCV. I will contact you directly in order to discuss your application and the possible compatible sample codes we might have.

A response from Julien at Thorlabs: A DirectShow device needs to be installed by hand during the software installation process, in order to be accessible. You should try to reinstall your software. During this installation, you will be prompted with a pop up window telling that there is no DirectShow device. By simply clicking add, you will then create a new DirectShow device which you will then be able to access. Should this approach not help, please contact techsupport@thorlabs.com for direct assistance.

Do you have any cross-platform sample code using the DCC1545M with OpenCV?

I am having trouble with DirectShow drivers on Windows 7 64bit. Do you have a more recent Win7 64 bit release? The camera works fine using Thorlabs Viewer, and reasonably well through custom software that uses Thorlabs API, but Direct Show device is not found.

Response from Buki at Thorlabs: Thank you for using our Feedback Tool. The software package supplied with the camera can take a snapshot either manually or by triggering signal. Please contact TechSupport@thorlabs.com if you have further questions.

Response from Buki at Thorlabs to Tsong-Shin: Thank you for using our Feedback Tool. Please see the answers to your questions below and contact TechSupport@thorlabs.com with further questions: 1. The A/C converter resolution is 8 bit because of the USB connection. 2. S/N ratio of the sensor is 44dB max. This information is included in the sensor manufacturer spec sheet for the DCC1645C: http://www.thorlabs.com/Thorcat/19400/19417-M01.pdf 3. No additional accessories are needed. You many need a Ø1/2"post and Ø1/2" post holder to mount the camera on the breadboard. You can find them on our website at http://www.thorlabs.com/navigation.cfm?Guide_ID=52.

Can I get a snapshot or capture a image with this divice?

Dear Sr., I have some problem about DCC1645C In the spec."A/D Converter Resolution", it is "10 Bit (8 Bit Max With USB Connection)". This divice uses USB interface, so this means it is 8 Bit, right? Do you have the data of S/N ratio of this divice? If I buy this divice, do I need to buy any other accessories? Thank you for your information. Tsong-Shin Lim

A response from Julien at Thorlabs: Dear Stephen, this camera has as of now not been tested with Matlab. We provide C++ example programs that can be used within Matlab but there is no direct Matlab support for those cameras.

Hi, I want to buy the MVL35M23 and the DCC1545M and use them together. I will need the camera to be compatible with Matlab software, since I will be using Matlab algorithms for focus adjustments. Will I be able to use Matlab with this? Thanks, Stephen

Response from Javier at Thorlabs to huw.major: Thank you for submitting your request. Unfortunately, the glass filters of the DCC1545C and DCC1645C CMOS cameras cannot be easily removed, as they are glued to the housing.

How easy/feasible is it to remove the glass cover from the monochrome camera? I am not bothered that the removal cannot be reversed. I want to eliminate etalon effects, but cannot stretch my budget to the CCD version of the camera. Thanks

Thank you for your feedback. We provide direct support for those drivers. Based on the exact nature of your problem, we could send you the newest version of our driver, which solves a couple of windows 7 related issues. Should this not help further, we could also have two engineers log onto your system through VPN so that they could help directly with the troubleshooting. We will proceed and send you the new driver as soon as we have your contact information. Please contact techsupport@thorlabs.com.

We have purchased three cameras for our experiments and hope to use it to build prototypes. However, the Labview driver does not work well on our Windows 7 64bit PC. It stops working when you change the camera settings. We have to unplug the USB cable and restart the program when that happenes. We have communicated with the customer support for awhile but did not get the issue resolved. We really need the person who developed the Labview driver to communicate with us so that the camera can be useful.

Response from Javier at Thorlabs to grjgordo: Thank you very much for submitting your inquiry. All camera settings can be set either to automatic or to manual. Concerning the contrast, several parameters can be set manually when autocontrast is deactivated. This includes gamma, gain (for each color when using a color camera) and dark level. Those functions can be accessed by going into the device properties under the tab "Image". You can go to page 49 of the manual for more details. I will contact you directly in case you have any further questions.

First of all this is an excellent little camera and software for the price. However, is there any way you can adjust the contrast on this CMOS camera manually. The auto-contrast feature does not work very well. In the histogram showing the distribution of pixel intensities from 0-255, almost all of my pixel values are in the middle of the range for the preparation I am looking at. If I could simply manually adjust the contrast to spread the pixel histogram out my image would look much better. Is there any way to do this? Thanks

It doesnt matter what you set the frame rate to since the actual transfer is limited by the USB data transfer. With several USB devices connected most PCs transfer via USB about 12 frames per second. You can run two instances for two cameras but the frame rate drops even more. USB is a shared commodity so the more peripherals, the slower it gets.

hi, i am running DCC1545 cameras in the labview program given in your downloads, how can i run two cameras simultaneously? i have tried renaming the dll and setting different Camera ID for the same code copied twice. thanks.

Response from Tor at Thorlabs to Vivian: Thank you for your inquiry. The area of interest of the camera can be set from the software directly from the task bar menu as explained in section 6.2 of the manual (http://www.thorlabs.de/Thorcat/19400/19418-D02.pdf). Also the option "show only Area of interest" from the view tab should be selected. In order to set allow an as fast as possible data transfer from the camera to the computer, the pixel clock should be set to its maximum value. Also the exposure should be set to the fastest value possible given the amount of light to be detected. Finally, any reduction of the amount of data to be transferred will increase the number of images per second that are sent to the computer. This can be achieved by reducing the AOI or by increasing he subsampling (section 6.4.3 of the manual)

Response from Response from Tor at Thorlabs to Geis: The current software version supports all Windows OS, up to Win 7 64-bit. Please try to reinstall the software with the version available from our website. If you experience further difficulties, please contact techsupport@thorlabs.com for troubleshooting.

Response from Tor at Thorlabs to unknown poster: DirectShow Editing Services (DES) is an API targeted at video editing tasks and built on top of the core DirectShow architecture. Please email techsupport@thorlabs.com if you have additional inquiries.

Response from Tor at Thorlabs to unknown poster: The first camera can be connected directly. Cameras #2 - #4 must connected each to a separate USB hub. The frame rate depends on the PC performance and how the LabVIEW application is created.

Hi, how can i set region of interest for capture using camera DCC1545C? Do you have any suggested configuration to run camera at its fastest speed possible? thanks

Thorlabs I was running your High Resolution USB2.0 CMOS Camera, 1280 x 1024, Monochrome with windows XP and fusion on a mac. Since then the XP was up-graded to windows 7 and the camera will not run. Do I need an additional driver? Please some advice. Thanks Mike Geis

I been using existing cameras in my application using DirectShow. This camera doesnt support more than one resolution like all the other cameras I have used, in order to reduce the resolution I would have to set up subSampling. Is there any way I can do this in directshow directly?

I am interested in running 4 DCC1645C cameras through a laptop running labview. I have 4 USB ports available. Is it possible to run 4 of these cameras on a computer, and how close can I expect time alignment in the frames from the different cameras to be at 25fps. thanks.

Response from Javier at Thorlabs to lgs125: We have corrected the file download. Please download the software again; the file can now be unzipped without any problems.

A response from Julien at Thorlabs: The camera needs a given bandwidth in order to work properly. When a USB hub is used for the camera plus another device, the bandwidth sharing will in most cases lead to errors from the camera. The easiest solution is to dedicate one full USB port to the camera.

Hi, camera works great on its own. But I run into connectivity problems when using other USB DAQ cards through a hub (NI-6501). When camera and two DAQ cards are plugged directly into labtop, everything works fine. Camera + hub (nothing in hub) camera works. Camera + hub + plugging in a DAQ card freezes the video until I unplug the DAQ card. My hub is powered (5V 3 amp max) so I dont think its power related. Same problem occurs when using an ocean optics spectrometer instead of the DAQ card peripherals... Any suggestions?

I am attempting to download the included software and windows drivers for this camera, as I have misplaced the installation disk. However, when I attempt to unzip the file, I am unable to do so. Has anyone else had this problem? This has occurred on both a Linux and Windows machine. Thanks.

A response from Julien at Thorlabs: the damage threshold of our cameras is close to that of standard Si diodes (~100 mW/cm^2. The exact value can vary from camera to camera due to the manufacturing process. I will contact you directly to further discuss your application in order to see if this can be achieved with these cameras.

Is there any information for the damage threashold? Wed like to use it as a laser spot-size measurement device. Thanks.

A response from Julien at Thorlbas to Johane: Did you try to set the frame rate at its minimum value? The software of the DCx cameras is written in such a way that one first sets the frame rate to a fixed value and the exposure time can then be set within the range that allows the camera to operate at this given frame rate. About your other question, it is not directly possible to change the camera ID in Labview but you can do it through the camera manager. This procedure needs to be done only once since the camera ID is directly written in the EEPROM. I will send you an email with a prerelease version of the Labview manual and the exact procedure to change the camera ID.

Response from Javier at Thorlabs to p.lanigan: Thank you for your feedback. The current DCx camera software does not support 64bit operating systems yet. However, we are working on a software upgrade which will be compatible with this interface.

I cannot seem to run the uc480livestream.vi examples from LabView 2010 64-bit as it appears the library function uc480_LabVIEW.dll has not been updated for the 64-bit version. This is used in SetImageMem.vi, GetActImgMem.vi and SetAllocatedImageMem.vi, can someone help please?

Johan asks... Is there any documentation available for the DCC camera Labview interface? Why is the maximum exposure time that can be chosen for the color version through the labview interface limited to approx. 0.5s, at the lowest pixel clock frequency, instead of 10s as stated in the specifications? What other parameters limit maximum and minimum exposure times? Is there any way to change Camera ID through the Labview interface?

Response from Javier at Thorlabs to ako.chijioke: Thank you for your feedback. The DC1545M is sensitive in the 400-900 nm range. I will send to the sensitivity curve shown on page 100 of the manual (Documents and Drawings Tab).

Hello, what is the wavelength response curve of your cMOS camera DCC1545M? thanks

Response from Javier at Thorlabs to nadoluvalentin: thank you for your feedback. Page 97 of the manual shows a relative response curve for the color and monochrome CMOS cameras. I can also send you a quantum efficiency curve of the sensor.

Is the response curve of the DCC1645C camera available? Im trying to write a laser beam analyzer software that can also estimate laser beam power output. Thank you! Val

a resonse from Julien at Thorlabs: Dear Andrea, the software and drivers for the DCC and DCU cameras has been updated about a month ago. The version available on our website is now compatible with windows 7 both 32 bits and 64 bits.

Could you post online or send me the updated driver for the DCC1545M for Windows 7 - 64 bits. Thank you Andrea

A response from Julien at Thorlabs: USB uses a tree topology and is host controlled. That means that a PC with host functionality is required for the DCC and DCU cameras. With hubs and/or repeater the root hub’s connection facilities can be extended. Therefore in order to connect two DCC1545M to a computer, the first camera can be connected to the computer directly and the second needs to be connected through a USB hub. About your second question, the UC480 viewer does not offer the possibility to display false color image. However, an extensive function library as well as several example programs can be used to easily obtain this type of images in other environment, like for instance Labview.

I have two questions about the DCC1545M CMOS cameras: 1-I have a laptop with a USB 2.0 PC Card Adapter, can I run two cameras simultaneously from this one single laptop using the USB adapter? 2-is it possible to display false color images on the monochrome version with any live demo program that is included with the camera software? Thank you. Catalin

A response from Adam at Thorlabs to info: I am glad to hear that the camera works great. I will send you an email with a link to the site where the drivers can be found.

Hi Jens. Just got the DCC1645M, wonderful camera! Could you please send me the preliminary drivers for Windows 7?

A reply from Jens at Thorlabs to Michael: the windows7 driver version has not been fully released yet, due to which it is not available on our web page. I will however send you the preliminary version of the driver in caes you would like to work with it already.

Is it possible to download the updated drives for windows 7 (64-bit) for the DCC1645C camera from somewhere?

A response from Adam at Thorlabs to utkin: The DCC1645C camera works with windows 7, but requires a driver update. I will email you with the driver update directly. The specifications stated online is incorrect. Currently the color and monochrome cameras only have a 8 bit resolution. We will update the website immediately.

I have 2 question. 1. Does DCC1645c camera (drivers and software) works with windows 7 (64-bit)? 2. In specs it is written that the camera has 10 bit ADC resolution. In the properties window (format) I could only find 8 bit options (RGB32). The ten bit option RGB30 is unavailable. How can I set 10 bit resolution? Or it is unavailable? What about DCC1545m monochrome camera? I appreciate your response. Thank you.

A response from Adam at Thorlabs to Sergey: We may be able to provice OEM prices, but would need more information. What type of quantities are you looking to purchase? What type of OEM features would you need? I will email you directly to get more information.

I wonder if you have OEM prices for DCC1545M CMOS cameras? If Yes, Could you provide with details, please?

A response from Adam at Thorlabs: The Monochrome Camera can be used with broadband light, 730nm-830nm as its spectral range is from 400nm-900nm. The color camera has an IR filter inside that is can be difficult to remove. The IR filter cuts off wavelengths past 650nm. While this filter can be cut out and removed, it can not be replaced after removing it. I will email you with more information about the spectral responsivity.

is it support broadband light. for example 730nm to 830nm broadband light. we want to use it for OCT imaging..............

A response from Juergen at Thorlabs to hchuaqui: Unfortunately, DCC cameras cannot be externally triggered, only internally (software trigger). However, this mode does not capture single images, but is doing that continuously, just with adjustable time interval between the images.. If you need single image capturing, I recommend the CCD cameras (monochrome: DCU22xM) - those have a hardware trigger input.

Is it possible to trigger the DCC1545M camera to obtain a single frame?

A response from Ken at Thorlabs to mokcay: A C mount adapter is included so any lens with CS mount or C mount will work. You can take a look at our MVL series camera lenses.

so where are the lenses for these CMOS USB2 CS mount cameras???

A reply from Jens at Thorlabs: we will correct this as soon as possible and send you a copy of the software in parallel.

link is broken to download driver/software. please fix.

Response from Juergen at Thorlabs to SergeyKostrov: I am sorry to inform you that we do not have data on sensitivity in Lux or Lumen. CMOS cameras use MT9M001 (Mono) / MT9M131 (Color) CMOS chips, but there are also no statements on sensitivity.

>> Regarding DCC1545M and DCC1645C cameras << How sensitive these CMOS cameras are? Could you provide me with Lux-numbers, please...
