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.
Note: Although special handling is required, acetone may be used to remove particles or debris from the windows.
