Zinc Selenide (ZnSe crystal)

Zinc Selenide (ZnSe crystal) is a synthetic material, with melting point 1517 C. It`s polycrystalline material. ZnSe belongs to the cubic crystal class 43m or hexagonal crystal class 6mm. Zinc Selenide is chemically inert, resistant to thermal shock. ZnSe has extremely low bulk losses, and is easily machined.

Optical ZnSe crystals have a transmission in a 0.6-15 microns range.

Application: optical components in CO2 laser processing.
