Description
- Useful transmission range covers 0.265-10 µm
- Most resistant to high energy radiation among fluorides listed in this catalogue
Barium fluoride (BaF₂) is used for optical windows, prisms and lenses transmitting from ultraviolet into infrared, it can be used as infrared laser window or lens. BaF₂ is recommended for use as a vacuum ultraviolet window where high radiation resistance is required. BaF₂ is less soluble than LiF, but relatively more soluble than MgF₂ and CaF₂.
