  • Wavelength region: 2.5 to 30 microns
  • CaF2, ZnSe, BaF2, Ge and KRS-5 (Thallium Bromide) substrates
  • Finer grid pattern for better low wavelength performance
  • High transmission
  • Extinction ratio > 90,000:1


  • Zinc Selenide’s transmission can be enhanced over a selected wavelength range, typically 9 to 11 microns, by an AR coating on the rear surface
  • Calcium Fluoride and Barium Fluoride have low refractive index values and do not see significant benefit from AR coatings
  • KRS-5 is not normally AR coated, because this would limit its broad transmission range, which is its primary advantage
  • Germanium polarizers are AR/AR coated to maximize transmission @10.6μ
  • Due to the manufacturing process ruled wire grid polarizers are not offered with AR coatings
