TECHSPEC® Zinc Selenide (ZnSe) Windows are ideal for a wide variety of infrared applications, including thermal imaging, FLIR, and medical systems. This chemically vapor-deposited material has wide usage in CO2 laser systems because of its low absorption coefficient and high resistance to thermal shock. Zinc Selenide (ZnSe) is a relatively soft material that scratches easily, and it is not recommended in harsh environments because its Knoop Hardness is only 120. When handling TECHSPEC Zinc Selenide (ZnSe) Windows, apply uniform pressure and wear Latex finger cots or gloves to prevent contamination. These windows are available uncoated or with broadband anti-reflection coating in diameters ranging from 5 to 127mm.
Note: Special care should be taken when handling Zinc Selenide as it is a toxic material. Always wear rubber or plastic gloves to avoid risk of contamination.
