Barium Fluoride – BaF2
lenses, windows, mirrors, filters and prisms
Used for optical windows, prisms and lenses transmitting from the vacuum ultraviolet into the Infrared. Barium Fluoride (BaF²) is also a scintillation material that exhibits one of the fastest known decay constants among inorganic materials.
Typical Applications: UV, Visible and Infrared imaging systems, scintillators, IR cut-off filters.
