Canon Optron donates artificially crystallized fluorite

2020-7-2  TOKYO, July 2, 2020—Canon Inc. announced today that its subsidiary company, Canon Optron Inc. has donated a synthetic fluorite crystal produced at Canon Optron's headquarters in Yuki City, Ibaraki Prefecture, to the Japan Camera Industry Institute (JCII).

Canon Optron developed a variety of other optical crystal materials while refining its high-temperature vacuum technologies and temperature control technologies for the mass production of synthetic fluorite. In July 2007, Canon Optron provided 12 lenses to the Smithsonian Astrophysical Observatory, including a synthetic fluorite element with a diameter of almost 40 cm, to be applied to observing signals from

Canon researchers, fueled by a strong desire to develop fluorite with their own hands towards developing high-performance lenses, succeeded in producing the first fluorite crystals synthesised in an electric furnace in March of 1967. In February of 1968, they established

Fluorite Canon HongKong

In 1968, two years after the initiation of the F Program, Canon researchers grew a synthetic fluorite crystal. But numerous hurdles remained before fluorite could be incorporated into a camera lens. Because fluorite cannot be ground in the same manner as optical glass, Canon relied on its legacy of lens grinding technology to develop a specialized technique for working with fluorite.

Even back in the 19th century, natural fluorite crystals were used in microscope lenses, but in nature, fluorite grows in very small crystals and it's not suitable for use in photographic lenses. To overcome this problem, Canon grows its own synthetic fluorite crystals in large enough quantities to create photographic lenses from them.

2020-12-7  Fluorite is a colorful mineral, both in visible and ultraviolet light, and the stone has ornamental and lapidary uses.Industrially, fluorite is used as a flux for smelting, and in the production of certain glasses and enamels. The purest grades of fluorite are a source of fluoride for hydrofluoric acid manufacture, which is the intermediate source of most fluorine-containing fine chemicals.
