Chapter 1 Overview
1.2.3 The Mirror
The mirror assembly is attached to the end of the actuator, and deflects the light beam
over the angular range of the motor shaft. Scanning galvo applications demand high
speed and frequencies of the shaft rotation, and so the inertia of the actuator and
mirror assembly can have a profound effect on the performance of the system. High
resonant frequencies and enhanced stiffness in the mirror assembly also add to
system performance by increasing bandwidth and response times.
Wavelength ranges and damage threshold of the different mirror coatings are details
below:
