Product Family Description

  • Multispectral 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 Multispectral 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 Multispectral is a chemical vapor deposited material which is commonly used in thermal imaging. With its excellent transmission properties in the visible and infrared, Zinc Sulfide Multispectral 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. TECHSPEC® Zinc Sulfide Multispectral Windows are offered uncoated or in a 3 - 12μm Broadband AR Coated Option. These windows are available in diameters ranging from 12.5 to 50.80mm with a 2, 3, or 4mm thickness.  

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