The RM25A Polarizer Rotation Mount allows 1 in. (25.4 mm) diameter linear polarizers, wave plates, Glan-laser calcite polarizers, and polarizing cube beamsplitters to be continuously rotated 360°. A graduated scale marked in 2° increments indicates angular position. Rotation can be locked to prevent accidental adjustment and reduce drift.
The RM25A attaches to ULTIMA^® optical mounts for precision tip/tilt and rotation. 8-32 tapped mounting holes are on one side and M4 tapped mounting holes are on the other. Three tapped holes per side permits secure mounting in industrial OEM optical systems.
A 1/2-in diameter polarizer or waveplate can be mounted to the RM25A rotator mount using the PRA-05 Adaptor, which screws into the rotator's 1.063-20 thread. The PRA-05 Adaptor included a retaining ring.
