Gimbal mirror mount with rotation provide 360 degree coarse positioning in two axes about the mirror surface in addition to fine adjustment of 6 degrees for theta x and theta y and 360° manual rotation with 1° resolution for theta z. Two types of fine adjustments are provided. 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 up to 12.5 mm thickness can be held in 50 mm Gimbal mirror mount and up to 10 mm can be held in 25 mm gimbal mount. In both models, optics are fixed with the help of threaded ring.
