OT1は、4つのRMSネジ切りポートが付いた小型のSM1ネジ対応対物レンズターレット(ホルダ)です。筺体は主にアルミニウム製ですが、インサート部分は高い耐久性と精密さが求められる戻り止め機構を実現するためにスチール製になっており、対物レンズには±2.5 µmの双方向の位置再現性があります。対物レンズターレットOT1の接続部分にはSM1ネジが付いているので、当社のレンズチューブケージシステムを使用したイメージング用システムに簡単に取り付けることができます。 OT1をケージシステムに取り付けるには、30 mmケージシステム用CP33/Mや60 mmケージシステム用LCP33/Mをお使いください。OT1は、水平または垂直方向のいずれかに対物レンズをしっかりと保持するように設計されています。

RMSCP1およびRMSCP2は、レンズターレットのポートや顕微鏡対物レンズなどのRMSネジ付き部品を不使用時に保護できる設計となっています。RMSCP2にはOT1のレンズポート用にRMS外ネジが付いています。また、RMSCP1には顕微鏡対物レンズ用にRMS内ネジが付いています。

また、当社では5個の対物レンズ用ターレットを内蔵する集光ブロック(ポスト取付け可能)もご用意しております。

Dear. please provide information how to make this stable as possible. I would use this in my transmission microscope and also measuring confocally so I can switch between objectives. And how they can be mounted, it is not possible to mount them on the side with post and potholder or something similar. Or you would suggest it would be best to use a lens tube or cage system. Asking mostly about practical solution with most stability. Thank you, Best regards

Hi, I use OT1 in my micro PL-Raman system (home-built with Thorlabs products). I am happy with Thorlabs products except for OT1. It is shaking. When I changed the magnifier from 10 to 20 or 50X the center is changing. You need to shake it to find the exact position, and you can find it if you are lucky. Please give me feedback on how am I going to make it tighten.

Do you have any microscope objective turret with RMS threaded mounting interface? Or else we can use an adapter with RMS external thread and SM1 internal thread like this: SM1BC, but we need to have long external RMS threading to make it eligible to handle the weight of turret with multiples objective. Please let me know if you have any alternative options?
jdelia  (posted 2022-05-11 03:55:18.0)
Thank you for contacting Thorlabs. We unfortunately do not have any alternative options, so an SM1-RMS adapter such as SM1BC would be needed in order to interface this part with internal RMS threads.

How can I make sure that OT1 is compatible with Mitutoyo components VMU-V (Mitutoyo product code 378-505) and Mitutoyo objectives M APO 5x (378-802-6), 10x (378-803-3), 20x (378-804-3) and 50x (378-814-4)
bhallewell  (posted 2018-02-27 10:14:41.0)
Response from Ben at Thorlabs: The OT1 is compatible with RMS-Threaded (0.800"-36) Objective Lens Ports. We have a range of adapters in the following link however for larger threads, the adapter may foul with the OT1 body itself. https://www.thorlabs.com/navigation.cfm?guide_id=2327

This product would be very useful if it came in an female SM1 version so that it can be adapted for using long working distance objectives with M26 x 0.706 threads.

Response from Alex at Thorlabs: Thank you for the feedback. We are always looking for new product ideas so it is greatly appreciated. I will follow up with our engineers since there is clearly a demand for this product.
k.zesewitz  (posted 2017-05-24 12:40:32.137)
Could you please do a female SM1-version of that on the lens side, finally? I saw that you're in the "process of reviewing this" since 2015. Is there any result yet? I mean a SM1 threading would make much more sense than RMS cause its still compatible to RMS but allows SM1 too.

Response from Ben at Thorlabs: Thank you for leaving this feedback. Unfortunately, we do not have any immediate plans to release this, however we are constantly working to expand our product line. Customer recommendations are an important part of this process, and I will reiterate this requirement to our engineers.

It would be very useful if you could make a similar turret but with female SM1 threads (on the lens side) rather than RMS. The vast range of your SM1 adapters would allow mounting larger diameters microscope lenses (nikon, mitutoyo,...) in addition to any custom made assembly based on your sm1 tubes. I'm aware you offer RMS to other microscope mounts but RMS is smaller than nikon 25 and mitutoyo 26mm diameter mounts. (I see someone else also suggested this version)

Response from Bweh at Thorlabs USA: Thanks for the feedback. We are in the process of reviewing this.

There is a lot of play in the turret, in that its rotation axis allows for some jiggling even after an objective has been clicked into place. I would estimate that the image (and thus the tip of the objective) can be translated side to side by +/- 0.5 mm based on the wiggle-room allowed by the turret rotation. Is there something I can do to tighten this up? We are operating in a manufacturing environment where there are lots of vibrations. The instability of the turret only adds to the image stability issues.

Response from Bweh at Thorlabs USA: This issue has been addressed in the new design. The OT1 mounting tube is bolted now. I will follow-up to address this issue with your unit.

Poster rickl (2008-03-21) pointed out a design flaw in the turret. Has this been corrected in the currently manufactured turret or is the design still incorporating glued sleeves?
rcapehorn  (posted 2015-10-02 10:25:48.0)
Response from Rob at Thorlabs: Thank you for your interest in our OT1. I can confirm that this issue has been addressed and that the turret tube is now screwed and bonded in place.
patrick.lu  (posted 2015-08-31 21:39:22.58)
We want to use one of these in conjunction with your LTFW6 light-tight filter wheel. Specifically, we would like to bolt the filter wheel to the top SM1 port of the OT1. I imagine a lens tube would be necessary between the OT1 and the LTFW6 to make the parts fit together? Seems like a simple adapter might not give enough clearance. What would you recommend?

Response from Bweh at Thorlabs USA: You may want to consider using an SM1V10
cbrideau  (posted 2015-07-30 12:24:48.42)
Still waiting for an SM1 version of this part. Given the wide variety of SM1-to-whatever adapters you have this would allow great flexibility in mounting objectives. RMS is just too small for modern lenses.

Response from Tim at Thorlabs: The RMS threads of the OT1 will hold the objectives snugly, and a typical set up can include a horizontal setup.

If I mount OT1 horizontally with 4 microscope objectives on it, can it hold them firmly without becoming loose?

Any chance you can make a linear version of this ? Like a filter slider with position detents used in many microscopes. The accuracy may increase.

Response from Javier at Thorlabs to last poster: Thank you very much for your feedback. We apologize about the inconvenience with your objective lens turret. We really have not experienced significant quality issues with this product, so it is most likely an isolated case. However, we would like to discuss this in detail with you, so that we can ensure your satisfaction with the performance of this part. Please contact us at techsupport@thorlabs.com and we will gladly assist you.

I purchased one to mount inverted. However the repeatability of 2.5 um is not what I observe. The turret is simply too loose and by lightly tapping on the side of a mounted objective the image will move and not return to the previous position. I tried to tighten the spring-loaded screw but it was only stable when it was so tight, that it couldnt be moved at all. It feels miles away from quality turrets from either Zeiss, Olympus, Nikon, which are much more solid in construction. I am hoping that it was a manufacturing error and that my next one will be of better quality.

Response from Tyler at Thorlabs to Rick: Thank you for informing us of this engineering failure. We are happy to hear that your optics we not damaged when the part failed. I have arranged for a second OT1 to be sent to you for free and you should receive it on Monday morning. We will also review the construction of the OT1 in order to eliminate this design flaw. Thank you again for the feedback, we always appreciate it when our customers participate in making our products better.
rickl  (posted 2008-03-21 15:26:39.0)
I purchased one of these turrets. I liked the simple design and compact 4 positions. UNFORTUNATELY there is a BIG manufacturing flaw. The threaded sleeve that is attached to the angled suface which holds the objectives is actually GLUED on, not threaded or bolted. The picture on the catalog page for this item shows some fairly nice objectives which could easily cost thousands of dollars. Im sure the owner of those objectives wouldnt be too happy to see his objectives crash to the ground because the glue didnt hold his turret together. Luckily, I only had the turret mounted (no optics) when mine broke. Ive since had my machinist bolt these two parts together, something Id recommend be implemented in your manufacturers process. I do need another one of these items, Id like to get a good discount on the next one if possible, since it requires about $100 of additional machining cost to mount the sleeve properly. Please let me know if this is possible. thank you, Rick Logemann BioImaging Solutions 858-356-0669 PH
