Scanning Mirror
Scanning Mirrors are precision optics for rapid and accurate beam steering. High reflectivity, low loss, low inertia and precise surface geometry maintain beam quality and positioning accuracy during high-speed motion.
Scanning Mirror Overview
Scanning Mirrors are precision optics for demanding systems requiring high reflectivity, low absorption, high laser damage threshold and excellent thermal stability.
Chenyu Optics manufactures scanning mirrors from fused silica, optical glass and silicon with custom size, shape, thickness, weight, surface accuracy and mounting geometry.
Dielectric HR, enhanced aluminum, protected silver and gold coatings support galvanometer scanners, LiDAR, marking, inspection and industrial beam-steering systems.

Scanning Mirror FAQ
What is a scanning mirror?
It is a lightweight precision mirror used to dynamically steer or scan a laser or optical beam across a specified field.
Why is low inertia important?
Lower rotational inertia supports faster acceleration and deceleration in high-speed galvanometer and beam-scanning systems.
Which substrate should I choose?
The choice depends on wavelength, dimensions, scan speed, thermal conditions and system requirements. Fused silica, optical glass and silicon are available.
Can scanning mirrors be customized for galvos?
Yes. Dimensions, shape, thickness, weight, surface specifications, mounting geometry and coating can be customized.
