PRODUCT OVERVIEW
Introduction
ZnSe windows are made from zinc selenide, an infrared optical material valued for its broad spectral range and low absorption. Its combination of visible-to-infrared transparency and favorable optical properties makes ZnSe a versatile material for infrared window components.
One of the key advantages of zinc selenide is its particularly low absorption around the 10.6 μm CO₂ laser wavelength. This allows ZnSe windows to handle infrared laser energy efficiently while limiting unnecessary heating and optical loss, giving the material a distinct advantage in laser-oriented optical designs.
Applications
- CO₂ laser protective windows
- Thermal imaging camera windows
- Infrared sensor protection windows
Features & advantages
- Broad infrared transmission range
- Good chemical stability and environmental durability
