It's confusing that Thorlabs designed and manufactures a TLV-U-MF2 with many advantages over the OEM cube MDFM-MF2 (SM1 threads, a "simplified Assembly and Improved Filter Retention Compared to OEM Cubes") but, per YLohia comment posted 2019-08-05, made it incompatible with Thorlabs' own WFA2001 and WFA2002. Any chance to make the TLV-U-MF2 compatible with the WFA2001/2? (from the CAD drawings it's not obvious what makes them unfit).

Hello Ludo, thank you for contacting Thorlabs. According to the specs, this product should be compatible without any issue.

What is a model name of filter cube for Zeiss microscope (Axio Imager Z2 or Z1)
YLohia  (posted 2021-05-20 10:33:43.0)
Thank you for contacting Thorlabs. Unfortunately, these filter cubes are not directly compatible with Zeiss microscopes. We will consider offering versions of these compatible with Zeiss in the future.

For your "customer inspired" section: It would sometimes be useful for some applications to be able to buy Filter Cubes that hold thicker Dichroics (2-3mm)
YLohia  (posted 2020-03-09 02:43:45.0)
Hello Michael, thank you for your feedback. I have posted your suggestion on our internal engineering forum for further consideration as a future product.

Is tlv-te2000 compatible with eclipse 80i microscopes?
YLohia  (posted 2019-10-17 10:15:18.0)
Yes, the TLV-TE2000 is indeed compatible with the Nikon Eclipse 80i microscope. This information can be found in the Overview tab, under the "Compatible Microscopes" column of the specs table.

We do not think this does not happen "The TLV-U-MF2 is not compatible with the WFA2001" But we would like to confirm.
YLohia  (posted 2019-08-05 04:09:08.0)
Hello, thank you for contacting Thorlabs. We could not find a reference to the statement, "The TLV-U-MF2 is not compatible with the WFA2001" on our website or documentation. That being said, this cube is not compatible with the WFA2001. Please contact your local Thorlabs Tech Support branch if you have further questions.

Are there any Thorlabs adaptors to mount MDFM-TE2000 or MDFM-QFXL to 30-mm cage system?
YLohia  (posted 2019-04-17 10:56:04.0)
Hello, thank you for contacting Thorlabs. These cubes are designed to be interfaced with industry microscope and not intended to be used with our cage system. Is there any particular reason the DFM1 (filter cube designed for our cage system) wouldn't work for you?
wenzel.jakob  (posted 2018-03-27 09:43:17.953)
Can the Thorlabs-built filter cubes (e.g. TLV-TE2000) accommodate 25.4mm filters? (The use of SM1 retaining rings seems to suggest this, but I am not sure..)
tcampbell  (posted 2018-03-28 08:46:56.0)
Hello, thank you for contacting Thorlabs. Yes, our filter cubes have SM1 threading and are compatible with Ø25.4 mm (Ø1.00") optics as well as Ø25.0 mm optics. We will update the presentation to make this clearer. Keep in mind that the optic thickness should be no greater than 5 mm or 3.5 mm, depending on the side of the cube.

Dear ladies and gentlemen, can you please confirm that the filter cube TLV-U-FF is operating in the Olympus IX83 microscope. Kind regards André Klossek
nbayconich  (posted 2017-10-25 03:26:08.0)
Thank you for contacting Thorlabs. The TLV-U-FF should be compatible with all of Olympus's IX3 series inverted microscopes. If the TLV-U-FF does not fit properly in your IX83 we can accept a return. I will contact you directly with more information.

Is it possible to buy any of the filter cube components separately? Some of the emission filter holders for my Nikon (TE2000) filter cubes are broken, and I do not need the whole cube, just the emission filter holder bit.
tcohen  (posted 2013-11-21 11:39:48.0)
Response from Tim at Thorlabs: Yes, we can supply the individual components. I see you did not leave an email address for us to provide a quote, so please contact us at Techsupport@thorlabs.com if you would like to pursue this option.

Response from Javier at Thorlabs to Elisabeth.Liebler-Tenorio: Although we currently do not offer filter cubes specifically designed for Leica microscopes, we will look into adding these to our current line. In the meantime, I will contact you directly to help you find a solution for your application.
Elisabeth.Liebler-Tenorio  (posted 2011-07-13 13:51:56.0)
Can you offer also filter cubes for a Leica DM RBE microscope. Size of cubes "L", cubes A4, L5, N3 and Y5?
jjurado  (posted 2011-05-27 10:13:00.0)
Response from Javier at Thorlabs to anonymous poster: Thank you for your reply. Please contact us at techsupport@thorlabs.com to discuss the details of your application. Perhaps we can devise a solution for adapting these cubes to our cage system.
user  (posted 2011-05-27 00:28:43.0)
Youre missing the point. I have lots of preloaded Oly, etc filtercubes in microscope turrets and stored on the shelf. It would be nice to pop these into a tabletop adapter rather than taking the filtercube apart, extracting the filters, and then taking a Thor cage/cube assembly apart and then remounting them and reinstalling them in a Thor tabletop setup. A filtercube-ready adaptor would be much much more convenient.
jjurado  (posted 2011-05-05 11:17:00.0)
Response from Javier at Thorlabs to last poster: Thank you very much for your feedback. We actually offer a variety of components that allow for mounting dichroic filters (26-43 mm long) and 1" diameter excitation/emission filters onto an optical table. Please visit the link below and review the descriptions for part numbers FFM1, B5C, and C4W. These components can easily be mounted onto an optical table via an 8-32 threaded post. http://www.thorlabs.com/NewGroupPage9.cfm?ObjectGroup_ID=3929 Please contact us at techsupport@thorlabs.com if you have any further questions or comments.
