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 windows 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 windows are available from 13mm diameter up to 50mm and down to 1mm thick 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.
Note: Stectroscopic Standard Grade rectangular windows may be cut from the same sized diameter, so may have curved edges as a result. These types also come in drilled (with 30mm spacing)/undrilled versions for use alone or as a pair.
