Zinc selenide (Znse) is a kind of yellow transparent polytropism material, whose general crystallization pellet size is 70µm and transmitting scope is 0.5-15 µm. Generated from CVD method, Zinc selenide(ZnSe) has little impurity absorption and extremely low scattering loses. Due to the low absorption to 10.6 µm wave length light, it becomes the first choice to manufacture the optical component for high power CO2 laser system. In addition, it is also commonly used in different optical systems within its entire transmitting wave band.
