Axsys Technologies has applied extensive heritage designing and building opto-mechanical systems to the development of fast steering mirror technology. The single-axis and two-axis, flexure mounted, fast steering mirror (FSM) represents a compact, low cost, high performance design solution for a variety of emerging optical scanning and beam stabilization applications. Such devices may be used to correct for polygon cross scan errors in prepress imaging, acquire and lock beams within free space laser telecom systems, modulate tilt and cavity control in interferometers, maintain beam stabilization in the presence of thermal drift and vibration, and provide general two axis beam scanning.
