ZnSe ZnS window

  • Introduction



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


Hyperion Optics 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. When handling, apply uniform pressure and wear Latex finger cots or gloves to prevent contamination.



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.


  • Uncoated or with AR Coatings Designed for a Variety of IR Ranges
  • Minimal Chromatic Aberration Due to Low Dispersion
  • Ideal for Infrared Applications Requiring Rugged Optics



Hyperion Optics Germanium Windows are available off-the-shelf with three anti-reflection coating options: 3 - 5μm for mid-infrared applications, 3 - 12μm for broadband multispectral applications, or 8 - 12μm for thermal imaging applications. Due to its high index of refraction (around 4.0 from 2 - 14μm), an anti-reflection coating is recommended for these germanium windows for sufficient transmission in the region of interest. Germanium is subject to thermal runaway, meaning that the transmission decreases as temperature increases. As such, these germanium windows should be used at temperatures below 100°C. Germanium’s high density (5.33 g/cm3) should be considered when designing for weight-sensitive systems. The Knoop Hardness of germanium (780) is approximately twice that of magnesium fluoride, making it ideal for infrared applications requiring rugged optics.
