Description

Infrared CVD ZnSe window

* Low Dispersion
* Available Uncoated or AR Coated
* Ideal for Thermal Imaging, FLIR, and Medical Systems

Zinc Selenide Windows (ZnS Windows) are perfect for a wide variety of infrared applications including thermal imaging, FLIR, and medical systems. This chemical vapor deposited material has extensive usage in high power 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.

Note: Special care should be taken when handling Zinc Selenide as it is a toxic material. Always wear rubber or plastic gloves to avoid the risk of contamination.
