The customized optics lenses is welcomed.

CVD ZnSe (Zinc Selenide) optics is widely used in spectral range 0.6-16.0 microns as optical components in many infrared spectral devices, FLIR (Forward Looking Infrared) systems, thermal imaging equipment and medical systems. Due to low absorption of material the ZnSe optics is used for high-power CO2 lasers. The following infrared optical details are made of CVD ZnSe: different kinds of prisms, lenses, blanks and windows. All optical products are manufactured of the usual standard sizes and max sizes of CVD ZnSe details according to max available ingots - up to (250x500x20) mm.

ZnSe optical windows or plates have modification as plane parallel windows, wedges (wedged windows), protective windows and Brewster windows.

ZnSe plane parallel windows are widely used as transfer optics and substrates for a variety of applications, such as laser windows, mirrors, beamsplitters, plate polarizers, output couplers, dichroic filters and beam combiners.

ZnSe wedges (wedged windows) are used as transfer beam splitting or beam deviation optics.

ZnSe Brewster windows are uncoated windows used as output window of CO2 laser chamber for selection of s- and p-polarization of laser radiation. In this case the window beam incident angle equals Brewster angle. Also it's possible another application of Brewster window, namely pair of Brewster windows can be used as Polarizer-Analyzer-Attenuator of transmitted radiation.

ZnSe protective windows
 - uncoated or AR / AR coated windows designed to withstand the conditions in industrial operations.

ZnSe Spherical lenses. It's possible different ZnSe lenses configuration. ZnSe spherical lenses are used in infrared beam delivery systems for collimating, focusing, imaging and matching.

ZnSe spherical plano-convex lenses are used as the most inexpensive focusing transmitting optics (positive focal length). And for better focusing the lens convex surface should be turned to the incident parallel beam.

ZnSe meniscus lenses (spherical convex- concave lenses) are used as the better focusing optical component, which have minimal spherical aberration and so minimal focal spot size for incident parallel beam, (in case R1>R2 - positive focal length, positive meniscus).

ZnSe spherical biconvex lenses are used as focusing and imaging transmitting optics (positive focal length).

ZnSe spherical plano-concave lenses are used as diverging transmitting optics (negative focal length), for example: for compact collimating system.

ZnSe spherical biconcave lenses are used as diverging transmitting optics (negative focal length).

ZnSe CVD cylindrical lenses are used for infrared applications including CO2 laser optics: usually - ZnSe cylindrical plano-convex lenses and ZnSe cylindrical plano-concave lenses.
