Tip/Tilt optic rotation mounts provide precise control of polarizers on all three axes of rotation. 1 in. and 0.5 in. wave plates, polarizers, and beamsplitter cubes rotate over 360° smoothly with exacting tip/tilt control while this mount also offers an easier to read rotation scale and independent lock of just the rotation adjustment.

The GM-1RA Gimbal Rotation Mount provides tip/tilt positioning for 1 in. (25.4 mm) wave plates, polarizers, and beamsplitter cubes. This mount is unique due to its gimbaled tip/tilt mechanism which allows angular adjustment of the optic without unwanted translation. The rotation stage can also be removed from the tip/tilt mechanism by removing four screws, allowing the rotation stage to be reversed or used independently.
The GM-1RA mount features independent locks for all axes, maintaining stable optical alignment. Engaging or disengaging each lock has negligible influence on the other axes.
The GM-1RA mount features a slotted base plate as well as two threaded holes 1/4-20 and M6 at the bottom for maximized flexibility of mounting. The slotted base can be removed in space-limited applications.
The M1-1PR Kinematic Polarizer Rotation Mount combines the tip/tilt adjustments of a kinematic mirror mount with rotation adjustment of a polarizer rotation mount. The mount features precise 100 TPI adjustment screws for increased pitch and yaw sensitivity. Rotation on full ball bearing races can be coarsely aligned using the knurled edge of the rotating platform while fine adjustment with 4 arc min sensitivity is achieved by the knob. Angular position can be locked in place securely with the little screw in the center of the knob.
Both Tip-Tilt Optic Rotation Mounts hold 1.0 in. optic such as waveplates and polarizers securely in place 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
