- 360° of Continuous Rotation, Lockable
- 2° Graduations on Dial, Labeled Every 20°
The CRM1L 30 mm cage system rotation mounts for Ø1" optics provide 360° of continuous rotation with a locking screw to fix the position of the mount once the optic has been aligned. The smooth adjustment mechanism allows for precise positioning of wave plates, polarizers, and other polarization optics. The CRM1L has a double bored central hole for Ø1" optics where the optic is retained using a setscrew. The CRM1L rotation mount is compatible with Thorlabs' 30 mm cage system and can also be mounted on a TR series post.
