Product Description

Zinc selenide (ZnSe) Lens Features:

*Usable Transmission Range is 600nm to 16 micron
*Low dispersion
*AR coating for 10.6, 2-13 or 8-12µm
*Plano-Convex ZnSe lenses according to your design

Zinc Selenide (ZnSe) Lenses, which offer high transmission from 0.6-16 μm, are available with a broadband AR coating optimized for 2-13µm and 8-14µm spectral range deposited on both surfaces. This coating can be applied on upon request.

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 Zinc Selenide lenses are also particularly well suited for use with high-power CO2 lasers.
