China Zns Znse Laser Protection Window with Coating

Windows for infrared light,the transmission range is 0.5 μm - 22 μm. Used for high power CO2-laser optics at 10.6 microns. Zinc Selenide is produced by synthesis from zinc vapour and H2Se gas, forming as sheets on graphite susceptors.

In contrast to other optical materials for infrared light such as Ge (germanium), or Si (silicon), ZnSe windows allow transmission of some visible light, enabling easier adjustment (alignment) of the optical axis of infrared laser systems and enabling use of more convenient and cheaper He-Ne lasers.

Non-coated and AR coated products for CO2 lasers are available.

Never clean with acidic washing solutions.ZnSe is classified as a toxic material by law. Transactions involving ZnSe or products incorporating ZnSe require a certificate of transfer.Disposal of ZnSe optics as general waste is prohibited. Please notify us if you need to dispose of such products. (Ultiquest Technolgies products only.)Be sure to wear laser safety goggles when checking optical path and adjusting optical axis.
