Zinc Selenide is a chemically vapor deposited material commonly used in thermal imaging, FLIR, and medical systems. It has wide usage in high power CO2 laser systems because of its low absorption coefficient and high resistance to thermal shock. Zinc Selenide is a relatively soft material that scratches easily and it is not recommended for use in harsh environments (Knoop Hardness 120).
