Broadband Dielectric Mirror
Broadband Dielectric Mirrors are precision optical mirrors designed to provide high reflectivity across a broad wavelength range. They use multilayer dielectric coatings on optical substrates to achieve efficient reflection with low absorption. Chenyu Optics manufactures broadband dielectric mirrors in BK7 and fused silica with custom wavelength range coatings.
Broadband Dielectric Mirror Overview
Broadband Dielectric Mirrors are precision optical mirrors designed to provide high reflectivity across a broad wavelength range. They use multilayer dielectric coatings on optical substrates to achieve efficient reflection with low absorption.
With stable coating performance and excellent surface quality, broadband dielectric mirrors are widely used in laser systems, imaging instruments, spectroscopy and optical beam steering applications where consistent reflection across multiple wavelengths is required.
Chenyu Optics supports custom broadband dielectric mirror manufacturing according to customer drawings, including custom substrate material, dimensions, surface flatness and coating wavelength range for prototype and repeat production.
