Barium Fluoride - BaF2
Barium Fluoride (BaF₂) is an optical material with broad transmission from the ultraviolet (UV) through the visible and into the infrared (IR), spanning approximately 150 nm to 12.5 µm.
It is commonly specified for FTIR optics, space and radiation-hard systems, and broadband optical components where low refractive index, good UV performance, and stable transmission across a wide spectral range are required.
At Global Optics UK, BaF₂ components are precision-specified, supplied, and inspected to customer requirements, and are available as windows, lenses, prisms, and blanks, uncoated or with AR coatings.

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.
