Fluorite is fluorescent under ultraviolet light. Think the terms “fluorite” and “fluorescent” are a little similar? Well you’d be right! The term fluorescence actually gets its name from fluorine because the man who coined it was working with fluorine at the time.
So what’s fluorite used for? A whole bunch of things! It’s a major source of the commonly used hydrogen fluoride, and is used to make hydrofluoric acid. It’s also used in the making of steel and aluminum.
Fluorite can be used as a lens for a telescope of camera as well. These are generally used for specific scientific purposes, but some camera manufacturers have made fluorite lenses available.
