Barium Flint Glass

Barium Flint Glass

Barium Flint Glass is referred to as BaF glass. It is made by adding BaO, ZnO and other components to QF and F glass or adding PbO and other components to BaK glass. The dispersion is in the middle of these glasses, and the dispersion rises with the increase of the ratio of PbO to BaO. It is mainly used as a material for optical parts in optical instruments. such as Spherical Lenses, Cylindrical lenses.

By modifying the glass formula, the optical glass without lead, arsenic and cadmium and other radioactive elements is expressed by a prefix "H-" indicating its envioronment-friendly characteristics, for example: H-BaF2
