Front Surface Mirror
Front Surface Mirrors are precision reflective optical components used to control, redirect, focus or separate light paths in laser systems, imaging systems, machine vision and scientific instruments. Chenyu Optics manufactures Front Surface Mirrors on BK7 optical glass, fused silica, silicon, germanium or other optical glass substrates, with aluminum, silver, gold, dielectric or custom optical coatings.
Front Surface Mirror Overview
Front Surface Mirrors are precision reflective optical components used to control, redirect, focus or separate optical paths without the secondary reflections and image degradation associated with back-surface mirrors.
These mirrors are widely used in laser systems, imaging systems, machine vision, optical instruments, scientific research and infrared systems, where high reflectivity, low scattering and a stable, precision reflective surface are required.
Chenyu Optics supports custom Front Surface Mirror manufacturing according to customer drawings, including custom substrate selection, coating design, diameter, thickness and tolerance for prototype and volume production.
