Edmund Optics Inc. 50mm Diameter, Zinc Sulfide Cleartran Window, Uncoated NT66-203

Cleartran™ Grade Zinc Sulfide Substrate Low Absorption and Low Scatter from 0.4 - 12µm Available Uncoated or 3 - 12µm Broadband AR Coated Option TECHSPEC® Zinc Sulfide Cleartran™ Windows are manufactured from a water-free, multi-spectral grade of zinc sulfide that has low absorption and scatter properties over its broad transmission range of 0.4 - 12µm. Like our TECHSPEC® Zinc Selenide Windows, Zinc Sulfide is a chemically vapor deposited material which is commonly used in thermal imaging. With its excellent transmission properties in the visible and infrared, Cleartran™ is the material of choice for systems that have both visible and mid-wave or long-wave infrared sensors. It is slightly harder and more chemically resistant than zinc selenide.
