Zinc selenide dome cover

Due to its wide transmission band and low absorption in the red portion of the visible spectrum, Zinc Selenide (ZnSe) is commonly used in optical systems that combine CO2 lasers, operating at 10.6 μm, with inexpensive HeNe alignment lasers. Zinc selenide is transparent from 600 nm - 16 μm and is ideal for IR applications. It is also commonly used in thermal imaging systems. ZnSe also transmits some visible light, unlike germanium and silicon, thereby allowing for visual optical alignment. However, it is quite soft and will scratch easily. ZnSe has an index of refraction of 2.403 at 10.6 μm.
