Large Precision Gimbal Mirror Holders / MHD
Gimbal mirror holders designed for mirrors φ100mm to φ300mm.
These mirror holders can minimize optical path length difference, a problem in large mirrors,
caused by mirror tilt adjustment.
It is structured to fix the mirror with the three resin tip screws from the back, and it is designed to fix the mirror of various thickness.Differential micrometer heads with large knobs are used for fine angular adjustment.
