Barium Fluoride - BaF2
Barium Fluoride (BaF₂) is a versatile optical material with excellent transmission in the ultraviolet (UV), visible, and infrared (IR) regions — from 150 nm to 12.5 µm. It is widely used in FTIR spectroscopy, space optics, and high-power laser applications due to its low refractive index, high damage threshold, and good resistance to thermal shock. At Global Optics UK, we offer precision-fabricated BaF₂ windows, lenses, prisms, and blanks, custom-made to your specification and available uncoated or with AR coatings.

FAQ
FAQ
Q: What is Barium Fluoride (BaF₂) used for?
A: BaF₂ is used in spectroscopy, FTIR optics, IR and UV transmission systems, radiation detection, and aerospace targeting due to its wide transmission range and radiation hardness.
Q: Is Barium Fluoride suitable for IR applications?
A: Yes, BaF₂ transmits from 0.15 to 12.5 µm, making it ideal for IR windows and FTIR spectrometers.
Q: Is BaF₂ hygroscopic?
A: BaF₂ has low hygroscopicity. It is stable in dry environments but should be stored with desiccants to avoid moisture degradation.
Q: Can Barium Fluoride be used in scintillation?
A: Yes, it has fast scintillation decay (~0.6 ns) and is used in gamma and X-ray detection.
Q: Where can I find the technical datasheet?
A: You can download the BaF₂ datasheet here.
