Dichroic Mirrors
Dichroic Mirrors (Selective Wavelength Reflectors)
Dichroic mirrors (commonly referred to as color mirrors, wavelength-selective reflectors, or dichroic beamsplitters) are specialized optical thin-film components engineered to selectively reflect specific spectral wavelength bands while transmitting the remaining light spectrum with ultra-high efficiency.
Functions:
Utilizes precision multilayer inorganic dielectric interference stacks (PVD-EBGE) to achieve sharp transition slopes, minimal light absorption, and vivid spectral separation. Designed to withstand intense thermal dissipation up to 450°C–500°C without color drift, thermal warping, or film degradation under high-power LED light engines and HID gas-discharge illumination.
Applications:
Architectural floodlighting
RGB light engine combiners
Optical projection systems
Medical diagnostic instruments
Multi-channel machine vision illumination
Intelligent stage lighting luminaires
(moving head spots/washers, scanners, effect lights)

Information and Notes
1. The spectral reflection behavior and perceived color of dichroic mirrors shift dynamically based on the angle of incidence (AOI). Coatings are optimized for specific operational geometries: small angles (incident light at 5° to 45° relative to the mirror surface normal) and large angles (incident light at 45° to 70°).
2. Dichroic mirrors are manufactured via precision thin-film vacuum deposition, utilizing dielectric interference stacks typically comprising 18 to 32 layers to deliver sharp spectral edge transitions and maximum reflection efficiency.
3. Coating processes utilize high-vacuum Physical Vapor Deposition with Electron Beam Gun Evaporation (PVD-EBGE) technology, ensuring exceptional film density, outstanding thermal endurance (withstanding continuous operation up to 450°C–500°C), and zero color fading under intense light radiation.
