Dichroic Filters
Dichroic Color Filters (Selective Bandpass Optics)
Dichroic filters (also known as interference filters, dichroic color optics, or wavelength-selective thin-film bandpasses) are precision optical components engineered to transmit specific color spectra while reflecting complementary optical wavelengths with ultra-low thermal absorption.
Functions:
Manufactured using high-vacuum physical vapor deposition with electron beam gun evaporation (PVD-EBGE), these filters feature 21 to 42 inorganic dielectric film layers deposited onto high-end optical glass substrates. They deliver ultra-high light transmission, sharp edge transitions, saturated chromatic purity, zero color fading, and robust thermal endurance capable of withstanding sustained operational temperatures up to 450°C–500°C.
Applications:
Fiber optic illuminators
Architectural floodlighting
RGB light engine combiners
Optical measurement devices
Medical diagnostic equipment
Intelligent stage moving heads
Automated Optical Inspection (AOI) machine vision systems

Information and Notes
1. Dichroic color filters feature precision thin-film dielectric coatings comprising 21 to 48 layers vacuum-deposited on high-optical-quality glass substrates, delivering sharp spectral separation and maximum luminous efficiency.
2. Spectral transmission curves are optimized for normal incidence (0° angle of incidence, AOI). Operating at larger incidence angles causes a blue shift, shifting spectral edge characteristics toward shorter wavelengths.
3. Manufactured using high-vacuum Physical Vapor Deposition with Electron Beam Gun Evaporation (PVD-EBGE) technology, ensuring high coating density, excellent substrate adhesion, high thermal resistance (withstanding 450°C–500°C), and zero color fading over time.
4. Transmittance curves represent real physical sample measurements recorded at normal incidence (0° AOI).
5. Custom dimensions, non-standard shapes, and tailored spectral coating bandpasses are available upon request.
6. Thermal tempering or chemical toughening of glass substrates is subject to minimum thickness, size, and geometric shape constraints. Please refer to Introduction to Tempered Glass for technical details.
