Optical mount
Optical mount is a mechanical part of optical systems, determining the alignment, robust, and precision. Any variation would affect optical performance in geometric and these factors are vibration, temperature drift, acoustic fluctuation, shock, chemical corrosion...etc.
Mirror is particularly sensitive to any fluctuation because any geometric variation would amplify the change of optical path. For example, angle tilt of mirror causes reflection angle double.
