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) The CSM1-1 series is designed to connect two lens tube assemblies with internal SM1 threads at both ends. One end has a fixed thread length of 3.5mm, and the other end is available in different lengths, and a locking ring is attached to fix the attached component after adjustment, thereby limiting

the external thread depth of SM1 threaded components.

(2) The coupling adapter is threadedly mounted on the lens tube or other threaded components, so that the components can be engaged in the case of

rotation, and the position and angle of attachment to other components can be optimized.
