BaF2 Optical Crystals

Barium Fluoride(BaF2) has wide transmission range (200nm - 12μm) and low refraction index(1.48) which commonly used in windows, lens and prisms. It is suitable for infrared spectroscopy in the passive IR band between 8 to 14 μm, such as IR viewport window for thermographs. Barium fluoride windows can be used up to 800°C in a dry environment, but prolonged exposure to moisture can degrade transmission in the vacuum ultraviolet range. While barium fluoride windows are less resistant to water than calcium fluoride, BaF2 windows are the most resistant optical fluoride to high-energy radiation, but lower UV transmittance. Barium fluoride is also a fast scintillator which can be used to detect X-rays, gama rays and other high energy particles, uch as 511 keV gamma photons in Positron Emission Tomography (PET)
