Features

Lockable 360° Rotation

RM25 Optic Rotation Mounts are designed for 1.0 in. (25.4 mm) diameter polarizers and waveplates and feature a graduated scale marked in 2° increments to indicate angular position. Angular adjustment is controlled by rotating the barrel directly and can be locked in place with a set screw on the side. Three tapped holes per side permit direct integration with either imperial or metric optical system as well as secure mounting in industrial OEM applications.

Versatile Optic Mounting

RM25 Optic Rotation Mounts feature extra deep mounting barrel to hold 1.0 in. diameter optic such as waveplates and polarizers up to 0.5 in. thick with included retaining rings. Additionally, a variety of other optic in compatible adapter or holder can directly thread into the central 1.063''-20 aperture, for example, 0.5 in. optic in PRA-05 adapter, 0.5 in. beamsplitting cube in CH-0.5 holder, and Glan-Laser Calcite Polarizers such as 10GL08.

Compatible with 1 inch Mirror Mounts

The 1 inch diameter rear flange on both RM25A and RM25B can be mounted to a variety of standard 1 inch mirror mounts such as U100 ULTIMA® for precision tip/tilt and rotation.

Compatible with Cage System

The RM25B Optic Rotation Mount has special cutouts in its frame making it compatible with Newport's OpticsCage+™ Optical Cage system when mounted to OC1-DB cage mount.
