Zinc Selenide (ZnSe) Lenses

  • Low absorption in the red end of the visible spectrum
  • Not hygroscopic
  • Quite stable in the laboratory environment

Zinc selenide (ZnSe) is the most popular material for infrared applications. Due to a very wide transmission range covering 0.6-22 µm chemical vapor deposition grown ZnSe as a high optical quality material is used to manufacture optical components (windows, mirrors, lenses) for high power IR lasers.
