· ZnSe has high melting point administered, low thermal expansion coefficient, high hardness, good mechanical strength and wide optical wavelength. The transmissivity is more than 65% during 2~12um. In addition, ZnS has low
absorption on infrared wavelengths, and can transmit visible light. It’s the best choice to make infrared lens, windows, output coupling mirror and beam expander.
