Features

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

Anti-Reflective Coatings

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
