Product Specifications

Technical details and manufacturing context for Beam Steering Mirror

Definition
A beam steering mirror is a critical component within focusing optics systems that allows controlled angular deflection of laser beams or light paths. It enables precise alignment, scanning, or redirection of optical beams in applications such as laser processing, optical communications, microscopy, and measurement systems. The mirror's reflective surface is mounted on a mechanism that allows controlled rotation or tilting to change the beam's direction without significant power loss or distortion.
Working Principle
The beam steering mirror operates by reflecting incident light at a controlled angle. When mounted on precision actuators (such as galvanometers, piezoelectric elements, or motorized stages), the mirror can be tilted or rotated to change the reflection angle. This allows the outgoing beam direction to be precisely controlled while maintaining beam quality and minimizing aberrations. The steering mechanism typically provides angular resolution in the microradian to milliradian range.
