This series of ZnSe Laser Windows are manufactured especially for Co2 Laser applications. They are offered in both coated with an anti-reflectance thin-film coating applied to both surface, or uncoated which can be used for a variety of applications as they are. We can custom coat these for any wavelength or spectral performance you may require. In addition to the sizes listed below we generally have metric size diameters available such as 25mm, 50mm etc. Other diameters and thicknesses along with coating for other wavelengths can be custom manufactured quickly in our fabrication shop to your specific requirement.
