Dichroic filters
Dichroic Color Filters (Multilayer Thin-Film Optics)
Dichroic filters (also known as interference color filters or dichroic mirrors) are high-precision optical filters manufactured using multi-layer dielectric vacuum deposition. Unlike traditional absorptive gels or dyed glass, dichroic optics selectively transmit specific visible wavelength bands while reflecting the remaining spectrum with negligible optical absorption.
Functions:
Delivers ultra-high peak transmittance, vivid spectral saturation, exceptionally sharp cut-on/cut-off transitions, and high thermal resistance (withstanding ambient temperatures up to 450°C–500°C). Engineered with inorganic dielectric thin films that eliminate color fading, degradation, or thermal burn-in under high-power illumination sources.
Applications:
Medical illumination
Architectural floodlights
Entertainment effect lighting
Precision optical equipment
Color separation imaging modules
Professional stage lighting luminaires
Automated Optical Inspection (AOI) machine vision systems

Information and Notes
1. Dichroic color filters are manufactured using optical thin-film vacuum deposition, featuring precision multilayer dielectric stacks typically comprising 24 to 48 layers to achieve ultra-sharp spectral band separation.
2. Custom spectral bands, color chromaticity, and transmission characteristics can be engineered upon request, matching standard optical specifications or designated color reference codes (such as LEE Filters or Rosco color charts).
3. Advanced Physical Vapor Deposition with Electron Beam Gun Evaporation (PVD-EBGE) technology ensures high film density, exceptional thermal resistance (withstanding temperatures up to 450°C–500°C), and zero color fading under high-intensity light sources.
4. Spectral transmittance curves represent measurements at normal incidence (0° angle of incidence). Untransmitted visible wavelengths are reflected by the dielectric thin-film stack without absorption. Penetration color may shift slightly at oblique angles of incidence (blue-shift effect).
5. Physical chemical tempering or thermal strengthening applies to substrate processing with minimum dimension and geometric shape limitations. Please refer to Introduction to Tempered Glass for technical details.
6. Spectral curves display measured sample values and may exhibit minor tolerances between manufacturing production batches while strictly complying with defined optical specifications.
7. Dimension abbreviations: "Dia." or "Ø" denotes circular outer diameter.
8. Website specifications are provided for reference only. Final production and delivery comply with mutually agreed engineering specifications and actual physical products.
