Thermal Insulation Experiment
An experiment was conducted to compare the thermal isolation of our thermally insulating adapters (SM1A4TS, SM1A9TS, SM1A3TS, and SM1A10TS) presented at the bottom of this page with that of our traditional aluminum adapters. During the experiment, an aluminum adapter and a thermally isolating black Delrin®* adapter were each used to connect two lens tubes. Then, one of the lens tubes was externally heated to 60 oC using a foil heating element that had been attached to that lens tube’s outer surface.
During the heating process, simultaneous temperature readings were recorded in 30 second intervals for both the heated and unheated lens tube in each system. The measured results are shown in the plot to the right. From the graph, it is clearly evident that there is far less heat transfer when using one of our thermally isolating adapters to connect two lens tubes than exists when using an aluminum adapter.

Thorlabs' Threading Specifications
Thorlabs' lens tubes utilize a series of non-standard threadings. Threading specifications are given below for our SM threadings utilized in our lens tube and cage system components so that you can machine mating components to suit your application. We also offer products with C-Mount and RMS threadings, and the specifications for these threadings are also given below. Please note that other manufacturers may have different tolerances for these threads. For other thread specifications that are not listed here, please contact Tech Support.

(posted 2020-12-15 05:04:56.24) Is SM30 = c-mount thread?
If so, why on earth don't you say so? You have other adapters labelled as c-mount. It would have saved me a lot of time if you'd mentioned it anywhere! YLohia
(posted 2020-12-15 02:39:48.0) Thank you for contacting Thorlabs. The SM30 thread is specified as M30.5 x 0.5 thread while the C-mount thread is 1.00"-32. Please refer to the Specs tab. These are not the same type and are not cross-compatible. Ray Harwood
(posted 2020-07-25 20:07:54.34) Can you help me? I’ve got a very similar retaining ring on an automotive mirror, being plastic with extremely narrow slots. Nothing I’ve tried will budge the ring. Can you point me to a tool that will fit something like this? At the moment I don’t have the specific diameter of the ring, but if there’s hope, I’ll measure! llamb
(posted 2020-07-29 04:15:33.0) Hello, thank you for contacting Thorlabs. If your retaining ring appears similar to our SM1A3 adapter, then our SPW801 adjustable spanner wrench is our best option for a tool to help remove the retaining ring. 万和 李
(posted 2020-06-12 22:17:02.917) The surface of SM1A9 is designed only for hand operation which can adapt to most conditions. But when it is screwed too tightly, we need wrench like SPW502 to help this, while there is no place for SPW502. So I am wondering if you can reconsider this problem. llamb
(posted 2020-06-15 03:42:32.0) Thank you for your feedback. We will consider this product suggestion. For the time being, you can also consider our TGP1 soft-jaw pliers to better grip the SM1A9 or your mating parts. user
(posted 2019-06-21 14:07:01.34) We are interested in mounting RMS-thread objectives to the SM1 system. This almost works for us, but we are not interested in thermal isolation but do care about stability. A similar part made of metal (something along the lines of M32RMSS) would be much better. YLohia

I am looking for adapter SM1 female (optical filter mount) to 1.25" male, which is M28.5 x 0.6
1.25" is commonly used in astronomy.
Can you make a new catalog part?
Best Regards, Vassili tfrisch
(posted 2018-03-21 04:54:16.0) Hello, thank you for contacting Thorlabs. Yes, we are able to offer custom thread adapters, but we would need you to provide a mating piece we can use as a part of the inspection and quality control process. I will reach out to you directly about your application. luciano.olivo
(posted 2017-10-18 09:07:31.66) This adapter could be used to mount one 1" or 25mm diameter filter on a Kowa LM50JCM camera but the internal thread is not deep enough (only 3.3mm) for both a filter and a threaded retaining ring, I had to glue the filter to the adapter. A deeper internal thread, 7mm depth (2mm for the ring and 5mm for one or two filters)would be useful for similar applications.
Thanks and best regards.

(posted 2017-12-06 02:08:11.0) Hello, Luciano. Thank you for your feedback. SM1A36 (ext M27x0.5 to in SM1) could be used with a short lens tube in order to provide the needed internal thread. For example SM1L03 has 7.6mm of thread depth. If you don't want to glue optics in the future, this may be helpful in your application. cafortin
(posted 2015-11-13 15:15:42.977) Hi, I would like to adapt line scanning cameras with large 16K sensors for machine vision that use M95x1.0 threads with Thorlabs SM2/SM3 tubing and caging system. Is this in Thorlabs' plan to develop adapters with M95x1.0 threads? jlow
(posted 2015-11-20 10:08:40.0) Tyler Morgus: Thank you for the adapter request. Thorlabs can add this adapter to our product line. I will contact you to get the details on the internal/external threading combination that you need. Tyler, Thorlabs Optomechanics Group etienne

Thanks. jlow
(posted 2014-11-06 01:52:14.0) Response from Jeremy at Thorlabs: SolidWorks do not allow saving for a previous version. However, you should be able to download the STEP file and open that in your current version of SolidWorks. severin.filser

(posted 2013-09-05 11:16:34.873) It would be useful to have an adapter to convert external SM1 thread to external SM05 thread. cdaly
(posted 2013-09-11 16:02:00.0) Response From Chris at Thorlabs: Thank you for your feedback. Our adapter SM1A1 has internal SM1 threads with external SM05 threads. If you would like to mate two components which have both external SM1 and SM05 threads, the SM1A1 adapter can be used with an SM05T1 to provide the necessary threading. If you would like the adapter to have external threading on both sides in order to mate two internally threaded components, this can be done by using the SM1A1 with the SM1T2 lens tube coupler. tony.hainsworth
(posted 2013-03-07 15:57:28.31) Hi, I am looking for a part similar to the SM1A9, but with both camera and SM1 tube threads external. We have actually had and used two parts just like this but need more now. I am sure we got them bundled with the CMOS cameras we bought from you but I just cannot find this part listed separately.
Tony cdaly
(posted 2013-03-07 09:54:00.0) Response from Chris at Thorlabs: Thank you for your feedback. We do not have a single adapter which has external threads for both C-Mount and SM1, but if you thread an SM1T2 lens tube coupler into the SM1A9 adapter, you can create the desired adapter. cdaly

Thank you for your feedback and your interest in our optomechanical adapters. We will consider your request as we continue to expand our selection of adapters.
As an alternative solution, please consider combining the following two products to get an overall effect of external SM05 and RMS threads:
SM05T2 - SM05 (Ø0.535"-40) Coupler, External Threads
http://www.thorlabs.com/thorProduct.cfm?partNumber=SM05T2
SM05RMS - Adapter with External RMS Threads and Internal SM05 Threads

Can you contact us with more information about the problem that you experienced. As a double check, the design engineer is looking at the files. If they find a mistake it will be fixed and updated on our server by tomorrow morning. Thank you for helping us improve the quality of our website. user

Thank you for your feedback. We will work on improving the clarity of the table so it is easier to determine the different threads and mounts. despinosa
(posted 2011-10-04 10:59:16.0) The table highlights (for determining which style of mount) on this page are a pretty subtle variation in brightness- might make it a little more obvious. jjurado

(posted 2011-08-03 09:25:00.0) Id just like to comment on the SM1A12. It would be nice if you could increase the length of the M25 threading, since Nikon objectives do not seat properly. I have to have the machine shop here modify these, which is a pain. jjurado

We will look into offering M27x0.5 adapters for use with our C-Mount DCC/DCU cameras and SM1-threaded components.I will contact you directly to keep you updated of the status of this project. ajh
(posted 2011-07-07 16:32:31.0) Please consider adding adapters to this range to cover more of the filter threads used by your C-mount camera lenses, e.g. M27 x 0.5 which is used by a number of the Navitar lenses. Adaptors between these threads and SM1 (at least) would be useful for integrating cameras into lens tube and cage mount based optical systems. Your DCU and DCC cameras are small and light enough to be mounted via the lens in this way, and it can often be convenient to do so. Buki at Thorlabs
(posted 2011-01-26 13:57:38.0) Thank you for your feedback. We have added the STEP file for the SM1A2. flickingerd

(posted 2007-12-19 16:50:53.0) In response to acables request, we have added two links to the couplers page on this page (one in the overview tab and one in the first subgroup). We have also added a link to the couplers page under the related items link. Since the couplers page is quite extensive itself (i.e. 3 subgroups), it did not seem advisable to just add those products to this page, as it would make the page quite long. Thank you for taking the time to help us improve our web pages. We hope that these new links make it easier for you to find the couplers the next time you visit our site. acable
(posted 2007-12-12 10:12:00.0) Please consider having the Lens Tube Couplers added to this page, ive looked for these a couple of time and always come back to this page to look for them. |
