  • 厚さ3 mmまでの長方形ダイクロイックミラーやフィルタなどの光学素子をマウント
  • SM1シリーズの4つのネジ切り加工されたスルーポートで発光フィルタと励起フィルタが取付け可能
  • 30 mmケージシステムに取付け対応
  • ケージキューブコネクタCM1-CCで2つのケージキューブを接続

ダイクロイックフィルタ用キューブCM1-DCH/Mは、長方形のダイクロイックミラービームスプリッタ銀ミラー、偏光バンドパスフィルタなどの長方形の光学素子で、幅36 mm 、高さ26 mm、厚さ3 mmまでの寸法の光学素子を、内部のクランプを用いて固定します。他のフィルタ用キューブに比べてコンパクトなため、ケージ部品同士の距離が近くなります。キューブの底面には、2つの六角皿ネジがあり、このネジを1.5 mmの六角レンチで緩めると底面がキューブ型の筺体からはずれて、内部のクランプを動かすことができるようになります(右下写真参照)。

また発光フィルタや励起フィルタを短いレンズチューブにマウントし、SM1シリーズのネジ切り加工が施されたポートに取り付ければ、蛍光イメージングフィルタのセットアップが完成します(「用途」タブ参照)。キューブCM1-DCH/Mでは、全ての面に4つの#4-40のネジ切り加工付きの穴があるので30 mmのケージシステムに取付けることができて、M4のタップ穴を使うとポストにも取り付けられます。このキューブは、下記掲載のケージキューブコネクタCM1-CCを使うと、つなげて使用できます。ケージキューブはロッドアダプタERSCBによってケージロッドとの接続が可能です。




CM1-DCH/Mでは、2つのレンズチューブSM1L03が使用可能で、ケージシステム内にイメージングフィルタのセットを組み込むことができます。発光フィルタと励起フィルタは、ケージキューブに取り付けられた長さ7.6 mmのレンズチューブにマウントできます。マウスを使って、画面上の写真にポインタを持っていくと、右側の表中にある部品に対応する箇所に色が付きます。

We bought a few of these. Here I list the issues with this CM1-DCH design: 1) The spring loaded clamping mechanism is too tight. It leads to fringes on the reflected light due to strain on the dichroic. I had to remedy this by adding some padding between the dichroic and mount. 2) The screws that are used to bolt the cuboid to the base plate strips super easily and completely wastes the mount. Until these issues are fixed, I won't be buying these anymore and will actively discourage my colleagues from procuring these parts. Given how expensive these parts are, one should've noticed these issues.

Thank you for contacting Thorlabs, and we apologize for the issues you are experiencing. Regarding the first issue, I have reached out to you directly to discuss alternative options with weaker springs. For the second issue, while this is not something we have heard of before, we can certainly look into ensuring this does not happen in the future. Thank you again for the valuable feedback.

Dear Thorlabs team, The two M2.5 flat head screws which hold the bottom plate with the rest of the cube are easily destroyable by screwing and unscrewing several time. The allen key doesn't fit well in the hex hole. As well, it would be great to have a way to orient the FFM1 inside the bottom plate (similarly to the 2 dots you have on the bottom plate and on the rest of the cube). Thank's

Thank you for contacting us here at Thorlabs with this good feedback. We have heard a similar type of feedback in the past with regards to the size of the hex hole in the securing screws. I have logged your excellent suggestion regarding the alignment dots to our product development forum. This would indeed create a nice and easy way to ensure a nominal angle, rather than having to carefully adjust it. Thank you again for the feedback. This only helps us to improve our products!

Hi Thorlabs. Could you make the same thing for the 60mm cage system? Many thanks.
YLohia  (posted 2021-04-05 02:11:07.0)
Hello, thank you for your feedback. We will consider offering a 60 mm version of this exact cage cube in the future. In the meantime, we do offer the DFM2 for such applications.

Hi, Is this product for the right turning of light beam? Can I use it as a left-turning mount? Thanks.
YLohia  (posted 2020-09-17 01:34:00.0)
Hello, thank you for contacting Thorlabs. This can be used in either scenario -- the direction of the reflection will depend on the orientation of the FFM1 in the cube mount.
Sami Arja  (posted 2019-11-12 20:14:11.947)
Dear Thorlabs, Is it possible to use the CM1 with BS013 by purchasing the bottom part separately? I am interested to know if I can have a cage mount that is compatible with both DCH/M and BS013. Your advice is highly appreciated. Sami
YLohia  (posted 2019-11-13 10:43:59.0)
Hello Sami, thank you for contacting Thorlabs. The CM1 cannot be used with the BS013 as we don't not offer suitable plates to adapt cubed optics to the CM1 system. We do, however, offer the CCM1-4ER, which would be a good fit for your application.
Gregor Jotzu  (posted 2019-10-18 09:19:58.903)
Dear Thorlabs Team, it would be great to be able to purchase only the part that holds the filter separately. I have a setup where we use the filter cube in a cage construction and it is possible to remove the filter. It would be great if one can replace the filter. I am aware of the DFM1, but there are parts of our seput where we prefer the CM1-DCH. Sincerely, Gregor Jotzu
llamb  (posted 2019-10-22 11:21:40.0)
Hello Gregor, thank you for your feedback. We can certainly offer the bottom assembly of the CM1-DCH as a custom product for now, and I have posted this idea in our internal engineering forum for further review as its own product release. I have reached out to you directly to discuss quoting the bottom assembly as a custom product for the time being.

I just bought one of this and I'm not loving this product. I had been considering using it in an OEM application, but the filter mount does not seem very stable. I can apply slight pressure to the edge of a dichroic installed in this unit filter rock between two positions. I'd like this product if the mounting of the filter in this mount could be more stable and secure for example more like the DFM1. I just don't 'need the kinematic mounting feature (or extra size and cost) of the DFM1.
YLohia  (posted 2019-08-01 10:50:07.0)
Hello, thank you for your feedback. We are always looking for different ways of improving our products. I have posted your comments on our internal engineering forum for further consideration.
schnell  (posted 2017-05-18 14:33:18.503)
How well do these cage cubes hold the rectangular plate beamsplitters from your catalog? I wonder if they provide a stable enough mount to serve as a beamsplitter for interferometry. Also, will the cube hold the plate beamsplitter well enough when mounted vertically, e.g. the output port is facing down? Thank you!
nbayconich  (posted 2017-05-25 05:57:11.0)
Thank you for contacting Thorlabs. I will reach out to you directly regarding the CM1-DCH mounting capabilities. We also have the DFM1 cage cube or the B5C1 cage cube optic mount for Ø1" diameter optics as alternative mounting options.
lothar.schmid  (posted 2014-09-26 22:49:51.087)
The protrusions on the bottom plate partly block the 1'' holes, so that lens tubes cannot be screwed completely in. filing the protrusions down a bit solves the problem, but that's not what I expected from a thorlabs product.
cdaly  (posted 2014-10-11 04:47:06.0)
Response from Chris at Thorlabs: I will contact you directly to discuss this. There should not be an issue when attaching a standard 1" lens tube (SM1Lxx) to the cube as seen in the overview tab of this webpage.
sharrell  (posted 2012-09-13 08:43:00.0)
Response from Sean at Thorlabs: Thank you for sharing your feedback. Even though you were able to find the information you needed on the lens tube compatibility, we'll endeavor to make this information more obvious on the page through adding additional photos of the cube with an SM1 lens tube.

I just realized my previous question is answered (in the affirmative) on the overview page. My apologies.

Can I mate a SM1LXX lens tube into one of the ports?
