    Information and Notes

  • 1. IR700C,IR900C,IR970C(Cold Mirror) with 40~52 thin film layers which vacuum-deposited on substrate.
  • 2. Option: Side2 with multi-layer Anti-reflection coating to reduce reflection from 4% to 0.5% for less reflect of image or light.
  • 3. Coating by PVD-EBGE (Physical Vapor Deposition-Electron Beam Gun Evaporation) .
  • 4. The transmittance curves are measurements at 45°of incidence angle.
  • 5. The transmittance curves are based on actual measurements and may be different with manufacturing lots.
  • 6. IR720H,IR760H,IR780H,IR850H(Glass Filters) absorbing the light in orange and red wavelength range and transmitting light in the blue wavelength region.
  • 7. The transmittance curves are based on actual measurements and may be different with manufacturing lots.
  • 8. Glass Filters are also called "colored glass filters" or "color filters" generically.
