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:
►Collimator adapter for Ø8mm~Ø12mm cylindrical components;
►SM1 (1.035"-40) external thread;
►Adjustable range: ±6° pitch/yaw;
►Multi-aperture optional: Ø8mm~Ø12mm, compatible with different components;
►Compatible with 30mm cage system;
(1) The adjustable collimation adapter has external SM1 (1.035"-40) threads, which can provide ±6° pitch/deflection adjustment for cylindrical components. Use cylindrical components such as lasers, fiber collimators or optics The element is integrated into a lens tube, cage system, or optical mount; when used with longer elements, the available space in the SM1-threaded lens tube may limit the adjustment range (providing ±5° pitch/deflection adjustment).
(2) The two adjusting screws on the front panel of the adapter are used to control the pitch and yaw, which are rotated by a 2.0mm hexagon wrench. The front plate of the adapter is also engraved with the pitch and yaw axis, and two holes for the snap ring wrench. Use a hexagon wrench to tighten the locking screw to fix the installed components.
(3) To install the adapter in the lens tube or other components, first screw it to the desired position and axial direction, and then tighten the lock ring close to the end of the lens tube or the mounting seat. The lock ring can ensure Install in a stable position.
