Fluorite has so many uses as a mineral, from toothpaste to flux to Teflon, but did you know that it produces one of the most clear camera lenses on the market today?
It’s used because its structure allows a window for both infrared and ultraviolet wavelengths to pass through thus creating a clearer sharper image. Now, no more green fuzz found in your images -Fluorite makes it disappear.
|Fluorite has a very low dispersion, so lenses made from it exhibit less chromatic aberration than those made of ordinary glass.|
With the advent of synthetically grown fluorite (calcium fluoride crystal), it could be used instead of glass in some high-performance telescopes and camera lens elements. Its use for prisms and lenses was studied and promoted by Victor Schumann near the end of the 19th century.
In telescopes, fluorite elements allow high-resolution images of astronomical objects at high magnifications. Canon Inc. produces synthetic fluorite crystals that are used in their more expensive telephoto lenses.
