Optical commonly used thread size standard

This is the unique thread of Thorlabs in the United States, not the commonly used optical thread. SM is the code for the thread of the sewing machine in terms of thread expression, but this company in the United States uses it to connect the internal and external threads of the optical lens and the sleeve. The nature of the thread is UNS, and the United States has a special thread with a tolerance accuracy of 2A / 2B. The special place of this thread is 40 teeth per inch regardless of the diameter.

The specific dimensions are as follows:

                                                                                              Description

(1) SM-RP1 is a lockable continuous rotating mounting frame, and the knurled dial of the mounting frame can rotate 360 ° continuously with 2 ° indexing. To facilitate the auxiliary alignment, the zero scale line extends to the outer edge of the SM1 screw hole, and the accuracy index is 1 °. At the same time, the bottom plate is engraved with a vernier scale dividing 5 minutes of arc. It is convenient for precise repeated positioning and fine angle adjustment. The top set screw is tightened with a 2.0mm hex wrench to lock the rotation of the mounting base.

(2) The center aperture has SM1 (1.035 "- 40) internal threads, which can be used to install optical elements with a maximum thickness of 11.5 mm and other SM1 thread components. The optical element is fixed by the attached 2 CSK3 snap rings.

(3) The bottom of the mounting frame is provided with M4 screw holes with a depth of 6.5mm. The installable extension rod shall be used for free space construction.
