Features

  • Adapters to Integrate SM-Threaded Components into OEM Applications
    • Internal SM05 (0.535"-40) Threading
    • Internal or External SM1 (1.035"-40) Threading
    • Internal SM2 (2.035"-40) Threading
  • Four Counterbored Mounting Holes for 4-40 (M3) Screws

Thorlabs' OEM Flange to SM Thread Adapters allow users to integrate SM-threaded components into existing systems. These adapters can be mounted to any device or enclosure using four 4-40 (M3) screws (not included). The mounting holes are arranged in a square; see the table to the right for the hole spacing on each adapter. The hole spacing on the SM1A53 also allows it to serve as an interface between custom-built setups with an SM1-threaded port and some Nikon Eclipse Ti nosepieces. Once mounted, any compatible SM-threaded components (such as lens tubes and accessories) may be directly mounted to the adapter.

Could you create SM2F1 but with external SM2 adapter instead of internal? (similar to SM1F2 but compatible with SM2 thread)

Thank you for contacting Thorlabs. While this is not something we currently offer as a catalog solution, I can certainly pass along your request to our design engineers through our internal suggestion forum. We would currently suggest using the stock SM2F1 along with an SM2 coupler such as SM2T2. This would give you the external threads you need. I have also reached out to you directly to discuss the feasibility of a custom part.
