Barium Fluoride
Barium Fluoride (BaF₂) is a crystalline compound used in optical applications across the NIR, VIS, and MWIR spectrums. With resistance to high-energy radiation and performance in dry temperatures up to 800°C, it's an excellent choice. However, in a moist atmosphere, VUV transmission degrades over time, and water corrosion occurs at 500°C. BaF₂ is ideal for VUV windows requiring radiation resistance, thermography, medical equipment, lasers, and astronomy.
