HEAR: High Efficiency Broad-Band AR Coating

This multi-layer broadband anti-reflection coating is used in visible display applications for contrast enhancement and glare reduction. It can be optimized for non-normal angles of incidence and for alternate wavelength ranges. It is used on glass substrates with refractive index of 1.45 to 1.58.


  • Contrast enhancement for visible displays Glare reduction
  • AR Coating for the fiber end Energy conservation for low light level applications
  • Environmental protection for sensitive glass types
