Hellma - Barium Fluoride Optical Material for VIS/IR - Brochure

Hellma Materials BaF₂ features an excellent transmittance in the VIS and IR spectral ranges up to 12µm. This allows the usage of BaF₂ as broadband optical material in the VIS and IR dual-channel systems for visible and thermal imaging. BaF₂ has a lower refractive index than many other optical materials. This reduces transmission losses caused by Fresnel-reflection.
