Spherical Mirror
Spherical Mirrors have concave or convex reflective surfaces formed from a section of a sphere. Controlled radius of curvature enables predictable focusing, expansion and imaging.
Spherical Mirror Overview
Spherical Mirrors are precision optics for demanding systems requiring high reflectivity, low absorption, high laser damage threshold and excellent thermal stability.
Chenyu Optics manufactures spherical mirrors from fused silica, optical glass and Zerodur with custom diameter, thickness, radius of curvature, focal length and surface specifications.
Aluminum, silver, gold and dielectric coatings support applications from UV and visible wavelengths through infrared laser, imaging and scientific optical systems.
Key Advantages of Spherical Mirrors
