Free-Space Rotation Mounts CMRMD2

The free-space rotation adjustment mount provided by LBTEK is suitable for mounting anisotropic optical components with diameters of Ø25.4 mm and Ø50.8 mm. It features 360° rotation with a scale accuracy of 2° per division, and a differential scale of 5′ per division. The side is equipped with a locking screw to secure the rotating body. The end face has two countersunk locking screws—when loosened, the dial can be adjusted independently for zeroing without affecting the optical component's position. This allows for aligning the optical axis of the waveplate with the dial after installation. Once the position is adjusted, tightening the countersunk screws fixes the dial in place. The base includes an M4 threaded hole for connecting to optical posts.
