Zinc Selenide Window (ZnSe) Description
Zinc Selenide Window (ZnSe) features the ability to withstand thermal shock making it an optical material in CO2 laser systems. The hardness is only 2/3 of multispectral ZnS, the material is soft and prone to scratches, and the material has a high refractive index, so it needs to be coated with an anti-reflective film on its surface to protect it and gain transmittance.
Window is one of the basic optical components in optics. It is usually used as a protective window for electronic sensors or detectors of the external environment. It is used to separate the environment on both sides, such as separating the inside and outside of the instrument, to isolate the inside and outside of the instrument from each other, thereby protecting the internal components. Windows do not change the system's magnification.
