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
