Barium Fluoride (BaF2) Windows

Barium Fluoride (BaF2) is the fastest known scintillator material and BaF2 windows and plates are used in VUV and infrared spectroscopy. BaF2 has excellent Transmission from 200nm – 12μm and resistance to high-energy radiation. The material can be used up to 800°C but can be subject to reduced transmission in the UV with surface damage in high moisture environments. Accessories for FTIR spectrometers include standard stock windows and demountable cell windows. BaF2 spectroscopic and view port windows are often used for 8-11 micron wave range for the high transmission. Applications for use also include thermography, Laser spectroscopy, astronomy and medical thermology equipment. These optical windows are very sensitive to thermal and mechanical shock.

Our Barium Fluoride windows and plates are made as diameters and squares to a standard stock range or custom made to your design.
