Optical Glass Properties

Anti Reflection AR Coated Glass and BBAR Coated Glass

Conductive Anti Reflective BBAR Coated Glass
Antireflection or anti-reflective (AR) coatings reduce reflection on optical devices while the high conductivity < 400 ohms allows for extremely-low-frequency to very-low-frequency (ELF/VLF) field suppression. Resistance uniformity > 90%.

ISO specified Durability of the Antireflection Coatings on AR Coated Glass:

  • Humidity: No deteriation after exposure to a humidity test at a temperature of 58°C and 95% relative humidity.
  • Abrasion Resistance: No damage after 200 rub test with cheesecloth.
  • Corrosion Resistance: No deteriation after exposure to a 24 hour salt fog test.
  • Coating Adhesion: No damage after snap test of firmly placed tape.
