This page contains all of our Optical Component Thread Adapters that feature SM1 (1.035"-40) threading. Adapters that have both internal and external threads are available, as well as adapters with two sets of internal threads or two sets of external threads.
For use with microscope objectives, we recommend our brass microscope objective threading adapters. They feature a lip to prevent the microscope objective from being threaded too far onto the mount, and their brass construction is harder than aluminum and less likely to bind to and damage the objective threading.
Our SM1 adapters are a subset of our entire line of optical component thread adapters. To view our entire line, please see our Interactive Adapters Selection Guide.

Unheated SM1 Lens Tube with Delrin® Adapter |
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.
