ZINC SELENIDE (ZnSe) OPTICS
Zinc Selenide is used for infrared windows, lenses and prisms where transmission in the range 0.58mkm to 22mkm is desired . The refractive index is near 2.4. Zinc Selenide has a very low absorbtion coefficient and is used extensively for high power infrared laser optic. It is non-hygroscopic. Zinc Selenide is a relatively soft material and scrathes rather easily. The low absorbtion of the material avoids the thermal runaway problem of Germanium. Zinc Selenide windows and lenses requires an anti-reflection coating due to its high refractive index if high transmission is required. Alkor Technologies manufactures ZnSe optical components: ZnSe window, ZnSe lens, ZnSe wedge, ZnSe prisms. We offer two types of ZnSe: CVD and PVD (ceramic PO4). The largest dimensions of ZnSe optics: Dia 100x15mm Main properties:
