Abstract

A precision mirror displacement assembly for controlling rotation of a mirror about a rotational axis to obtain a precise mirror orientation includes a mirror having an enhanced backside and a reflective front surface. The enhanced backside has a sufficient thickness to provide that attachment of mirror displacement control components, such as portions of actuator and position sensor assemblies, to the backside during manufacture of the mirror assembly does not cause distortion of the reflective front surface of the mirror. The enhanced backside also is of sufficient thickness to avoid distortion of the front surface based on interaction of the mirror with mechanical stops and actuator components that are attached to a base of a separate housing of the mirror assembly that opposes the backside of the mirror.
