CRD-S2 Cage Rotation Mount 60mm Cage System 2 Inch Frame SM2 Optical High Precision Mount for Optical Experiment Research

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 CRD-S2 swivel mount is designed to mount Ø2" (50.8mm) optics up to 13mm thick to the SM2 threaded (2.035"-40) swivel mount. Use the attached CSK4 SM2 snap ring to fix the optics, It also comes with a washer to protect the lens;

(2) It can be rotated manually by 360°, the scale on the dial is 2°, and every 20° is engraved with digital marks. The smooth rotating mechanism allows precise positioning of the rotating frame, and the nylon top wire on the side is used to lock the rotating ring of the mounting seat after rotating and positioning. This fixing screw can be loosened with a 2mm hexagon wrench.

(3) The mounting base is compatible with 60mm cage system. This mounting base has 4 Ø6mm through holes for the installation of Ø6mm cage rods. The mounting base is integrated into the cage system. The side set screws can fix the position of the cage rods. ;

(4) A 30mm cage assembly can be used in a 60mm cage system by matching the CSM-3060A cage adapter or CSM series lens tube connector.

(5) And you can use the M4 threaded mounting hole at the bottom of the rotating mount (with 1 M4 fastening screw) to install on a Ø12mm post, and the mount can be used in free space;
