Custom ZnSe windows are available in 3–6 mm thicknesses
Zinc selenide (ZnSe) windows are custom-manufactured as plano-convex, plano-concave, and wedged windows with coatings to achieve specific wavelengths from 7 to 11 µm. They are available in 3–6 mm thicknesses with surface finishes from 10-5 to 80-50 scratch-dig and flatness of 10 waves to 1/20th wave, and meet ISO-10110 specifications.
