Zinc Selenide is used in the form of optical windows in FLIR (Forward Looking Infrared) systems, as meniscus, spherical or cylindrical lenses and as resonator windows in CO2 lasers.
Knight Optical supply a range of quality Zinc Selenide lenses either from stock or custom made to your specification. Every component is individually tested by our highly skilled technicians in our state of the art metrology lab to ensure all components meet our high quality standards. Our stock lenses are available as 25.4mm (1") planoconvex type with diameters from 30mm to 500mm and cover the requirements for both laser and infrared grade CVD ZnSe. Contact our multilingual technical sales team and discover how Knight Optical’s high quality Zinc Selenide optical components and service can improve your instrumentation and supply chain experience.
