Information and Notes

  • 1. Cold Mirror with 40~52 thin film layers which vacuum-deposited on substrate.
  • 2. Option: Side2 with multi 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 incident angle.
  • 5. The transmittance curves are based on actual measurements and may be different with manufacturing lots.
