- Wide wavelength range of 0.2-11 μm
- Excellent as the sercurity inspection windows

Barium Fluoride is often suitable for applications in the passive IR band (8 to 14 μm) and is often used as a viewport window for thermal imaging inspection application in electric power facilities and petroleum indutries. For an equivalent thickness the transmission extends approximately 1 micron further into the IR than Calcium Fluoride. Hangzhou Shalom EO also provided the BaF2 windows with the protective coatings.
