High reflective filters
High Reflectance Filters (HR Mirrors)
Also known as High Reflection Mirrors or Dielectric Laser Mirrors.
Function:
Engineered specifically for high-precision green and red laser systems. Featuring ultra-high reflectivity ($R > 99\%$) and exceptionally low absorption, these filters minimize energy loss during reflection to ensure maximum optical efficiency and power preservation.
Applications:
Precision optics for Green, Blue, and Red Laser systems
LED illumination modules
Optical alignment devices.

Information and Notes
1. Angle of Incidence (AOI): Standard high reflectance filters are optimized for normal incidence (AOI 0°–5°) or 45° (AOI 40°–50°). Custom angles of incidence are available upon request.
2. Coating Structure: Vacuum-deposited with precision dielectric multilayer thin films to deliver ultra-high reflectance and minimal absorption across target bandwidths.
3. Deposition Technology: Precision optical coatings manufactured via PVD-EBGE (Physical Vapor Deposition - Electron Beam Gun Evaporation).
4. Custom Specifications: Standard web specifications serve as general technical references. Delivered products strictly comply with mutually agreed-upon technical drawings and parameters.
