more resistant than ZnSe, max. temperature for application: 300°C, reacts in combination with intense oxidizing agents and some acids, CVD grown plates. 

Remarkable 
  • Polycrystalline material produced by CVD process (Chemical Vapor Deposition)
  • Available in large plates  (price correlates with the thickness of the plate)
  • Two different qualities - ZnS (ms) and ZnS (FLIR) - which differ by their transmission properties
  • Use for the wavelength range from 350 nm-14 µm for ZnS-ms and 400 nm-12 µm for ZnS-FLIR
