Product information

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:

Characteristic

►Compatible with 30mm cage system;

►The 30mm cage coaxial system components can be rotated around the optical axis;

►Ø12mm post can be installed through the M4 screw hole at the bottom;

►The inner panel has a 360° laser scale for reading alignment;

► Rotation lock through flexible mechanism;

Description

(1) The CSJ-R1 rotating cage plate allows the entire 30mm cage coaxial system to rotate around the optical axis. It contains two cage plates: one is connected to a fixed cage structure section, and the other allows all the cage components connected to it to rotate. And the inner panel is laser-engraved with a 360° scale with 2° divisions, which can realize accurate manual positioning.

(2) When rotating the cage section between two fixed cage structure sections, the rotating cage section is extremely suitable for multiple optical components that require the same rotation angle (for example, using two lenses to change the space of a laser beam Spot distribution or multi-element polarization applications). After the position is adjusted by rotation, a 2mm hexagon wrench can be used to adjust the corresponding flexible locking mechanism to fix the rotation position.

(3) The center of the rotating cage plate has a 25.4mm deep SM1 (1.035"-40) threaded hole that penetrates the entire cage plate, so that the cage plate can still be rotated without deviation. The cage plate comes with two CSK3 snap rings , Ø1" optical lens can be installed directly.

(4) The front and rear panels of the cage plate are equipped with 4 Ø6mm through holes for installing Ø6mm poles. The cage rods at the front and rear ends must be interrupted at the cage plate. Use a 2mm hexagon wrench to fix the position of the support rod with the tightening screw on the side.
