Gimbal Mirror Mounts

GMM Series

Provides +/- 60 fine adjustment
Fabricated from Black Anodized Aluminum


Gimbal mirror mounts provide 360°coarse positioning in two axes about the mirror surface in addition to fine adjustment of 6°. Two types of fine adjustments are possible, one is micrometer drive with 10 micron least count and the other is with lead screw of 0.25 mm linear resolution per rotation. Switching between coarse and fine movement is by using a knob or a set-screw provided on the gimbal mount.

Optics upto 12.5 mm thickness can be held in 50 mm gimbal mirror mount and up to 10mm can be held in 25mm gimbal mount. In both models, optics are fixed with the help of threaded ring.
