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:
(1) The FWO-B filter wheel is compatible with 30mm coaxial system, with six filter holders with SM1 thread, the filter wheel is positioned by the internal small steel ball mechanical bayonet, and the filter center is aligned Cage system. Holds Ø1" optics up to 4.5mm thick and secures the lens with the included retaining ring.
(2) The fixed input and output ports on the body also have SM1 threads for compatibility with our Ø1" lens tubes. There are set screws on the side of the through hole of the cage rod, and the position of the cage rod can be fixed by a 1.6mm hexagon wrench. (Note that the through holes cannot pass through the cage rods, as they will be blocked by the filter wheel.
(3) There are M4 and M6 screw holes at the bottom, which are convenient for compatible installation of optomechanical parts.
