BaF2 lenses
●  Wide wavelength range  of 0.2-11 μm 
●  Suitable for MWIR (3-5 μm) thermal cameras

Barium Fluoride can be used in the ultraviolet, visible and infrared spectral regions. Barium Fluoride has transmission above 90% between 0.25 and 9.5µm. Barium Fluoride is half as hard as Calcium Fluoride and also more susceptible to thermal shock. However, it is commonly used in cryogenically cooled thermal imaging systems. It is somewhat more expensive than Calcium Fluoride and not as readily available in large sizes. Hangzhou Shalom EO offer the BaF2 lenses used in MWIR (3-5 micro) thermal imaging applications.
