Visible-NIR Mirror
Visible-NIR Mirrors are precision optical mirrors designed to provide high reflectivity across visible and near-infrared wavelength ranges. They use multilayer dielectric coatings to achieve efficient reflection with low absorption and excellent optical stability. Chenyu Optics manufactures Visible-NIR mirrors in BK7 and fused silica with custom wavelength range coatings.
Visible-NIR Mirror Overview
Visible-NIR Mirrors are precision optical mirrors designed to provide high reflectivity across visible and near-infrared wavelength ranges. They use multilayer dielectric coatings to achieve efficient reflection with low absorption and excellent optical stability.
With stable coating performance and excellent surface quality, Visible-NIR mirrors are widely used in laser systems, imaging instruments, spectroscopy equipment and optical beam steering applications requiring reliable VIS-NIR reflection performance.
Chenyu Optics supports custom Visible-NIR mirror manufacturing according to customer drawings, including custom substrate material, dimensions, surface accuracy and coating wavelength range for prototype and repeat production.
