Zinc selenide (ZnSe) optical window
PRODUCT CATEGORIES
Zinc selenide is a very good infrared material. It has a wide light transmission range from 0.5 microns to 19 microns. Because of its good imaging and thermal shock characteristics, it is often used as the lens and window of carbon dioxide laser.
light transmission range: 500nm ~ 19000nm.
coefficient of thermal expansion: 7.6×10-6/k.
density: 5.27g/cm3
