Optical Component Threading Adapters

Features

Adapter Diagram
Internal to External Thread Adapters are Available in Two Styles
  • SM05, SM1, SM30, SM2, and SM3 Adapters for Constructing Lens Tubes Systems
  • Lens Tube Couplers Mate Similarly SM-Threaded Components
  • Adapters for Many Common Microscope Objective Standards
  • C-Mount (1.00"-32), T-Mount (M42 x 0.75), and Other Metric Adapters for Camera Bodies and Lenses
  • Thermally Insulating Camera and Microscope Objective Adapters Available
  • M36 x 1.5 Adapter for Beam Expanders

We offer adapters that feature internal and external threads, two sets of internal threads, or two sets of external threads.

Internal to external thread-to-thread adapters are either machined with both threads inline (type 1) or with the two threads connected by a flange (type 2, as shown in the diagram to the right). Type 1 adapters may be positioned anywhere along a threaded tube, while type 2 adapters can only be placed at the end. See the "Adapter Profile" column in the tables below for information on the construction style of each adapter.

Thermally Insulating Adapters
Adapters whose item numbers end in TS are thermally insulating adapters, constructed of black delrin rather than aluminum. These adapters are useful in situations where heat transfer between components could be a problem, such as camera sensors, whose noise increases with temperature. We currently offer thermally insulating adapters with RMS, C-Mount, and SM1 threads. See the Thermal Isolation tab above for more details and test data.

The following tables outlines the adapters on this page that are currently offered by Thorlabs. Click on this icon Click for Details in the tables below to view an application drawing of each adapter. We have a number of other threaded adapters that can be found on our Adapter Guide. If you do not see an adapter or combination of adapters appropriate for your application, please contact Technical Support.

Thermal Stability of Al and Delrin Adapters

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.

SM Series Threading Specifications

Thorlabs' lens tubes utilize a series of non-standard threadings.

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

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.

Response from Chris at Thorlabs: Thank you for using our feedback feature. At the moment, we do not currently have M28 thread adapters, but we are always expanding our line of products. I have submitted your request within our internal forums and it will be considered for release by our design engineers.

Do you happen to have M28 to C-mount adopter in the future? I know it is not a common thread (M28), but some ZEISS part use M28 threads and I really need it... Thank you!

A response from Tyler at Thorlabs: I looked at all the SM1A25 drawing files and they appear to be correct. 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.

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.

Response from Javier at Thorlabs to halvorsen: Thank you very much for your feedback. We will consider the possibility of adding more thread depth to the M25x0.75 side of the SM1A12 adapter. I will contact you directly to discuss your requirements.

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.

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.

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.

The TS Series of Thermally Insulating Thread Adapters has been designed to minimize the thermal link between SM1-threaded and RMS- or C-Mount-threaded components. Three machined contact pads, which are strategically located on each interface of the adapter, eliminate any direct thermal link between the mounted components. This feature, coupled with the low thermal conductivity of black Delrin, provides significantly less heat transfer between components. Please see the Thermal Insulation tab for more details on the performance of this series of adapters.
