In the early years of the 21st century the stepper market for calcium fluoride collapsed and many large manufacturing facilities have been closed.

The solid is isostructural with (has the same structure as) fluorite (calcium fluoride).

Uranium-doped calcium fluoride was the second type of solid state laser invented, in the 1960s.

This varies from several weeks in calcium fluoride to up to two years.

Fluorite was then shown to be mostly composed of calcium fluoride.

Formation of insoluble calcium fluoride also causes strong pain.

Foremost among them is calcium fluoride, a material that manages to bring the different wavelengths of light together.

Presumably they're using proprietary materials to produce the same effects as calcium fluoride.

A good high-refraction replacement for calcium fluoride as a lens material can be a fluorophosphate glass.

Fluorspar, or calcium fluoride, was mined in Hardin County until the early 1990s.
