Barium Fluoride (BaF₂) Windows are high-performance optical components made from crystalline barium fluoride, offering an ultra-broad transmission range from 0.15μm (VUV) to 12μm (LWIR). Their low refractive index (~1.48) delivers excellent transmittance without anti-reflection coatings, while superior radiation resistance makes them ideal for harsh environments. BaF₂ windows are widely used in spectroscopy, thermal imaging, and laser systems requiring multi-spectral coverage.
