Zinc Selenide (ZnSe) Plano-Convex Lenses, which offer high transmission from 0.6-16 μm, are available with a broadband AR coating optimized for the 2-13 or 8-12 μm spectral range deposited on both surfaces. This coating greatly reduces the high surface reflectivity of the substrate. ZnSe lenses are typically used as collimators for laser applications in the 0.6-16.0 μm spectral region. Due to the low absorption coefficient of ZnSe, these lenses are also particularly well suited for use with high-power CO2 lasers.
