Barium Fluoride (BaF2) Lenses

  • 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.
