Fluorite is a monocrystal that has low chromatic aberration while being much lighter than traditional optical glass, resulting in higher optical quality with less weight. Using a fluorite lens in conjunction with a glass lens can reduce chromatic aberration to extremely low levels. However, natural fluorite occurs in small sizes that are suitable only for use in small optical equipment such as the object lenses of microscopes.2 Sources

Fluoride glass is a class of non-oxide optical glasses composed of fluorides of various metals. They can contain heavy metals such as zirconium, or be combined with lighter elements like aluminium and beryllium. These heavier elements cause the glass to have a transparency range extended into the infrared … See more

Fluorite - Wikipedia
Fluorite is a major source of hydrogen fluoride, a commodity chemical used to produce a wide range of materials. Hydrogen fluoride is liberated from the mineral by the action of concentrated sulfuric acid:
CaF2(s) + H2SO4 → CaSO4(s) + 2 HF(g)
The resulting HF is converted into fluorine, fluorocarbons, and diverse fluoride …Wikipedia · Text under CC-BY-SA license- Estimated Reading Time: 7 mins
