ZnSe (Zinc Selenide)
is a standard material for use in CO2
lasers as windows, beamsplitters, output couplers or focussing lenses.
Because of its broad transmission range, its low absorption and scatter, ZnSe is a standard material for use from 500 nm up to 22 µm.
ZnSe is non hygroscopic, chemically stable unless treated with strong acids, and has a very high damage threshold.LASEROPTIK
offers a large selection of AR, reflecting and beamsplitter coatings.
