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.
