Optical Crystals
Fluoride crystal, typically exemplified by fluorite, has to be grown in a vacuum ambient atmosphere with a high temperature of 1,000°C or higher, requiring advanced devices as well as high-level processing technology. Canon Optron succeeded in mass production of fluorite in 1968. Since then, we have continued to provide a wide range of optical crystal materials that are produced using our long accumulated technologies for high-temperature vacuum and temperature control. These crystal materials demonstrate the optical properties not found in conventional optical glass, and are widely used in optical devices such as telephoto lenses as well as analyzers, helping to dramatically expand the potential of optical equipment.
Products
CaF2
Used on telephoto lenses and other products such as zoom lenses, television cameras, and astronomical telescopes.
BaF2
Barium fluoride is commonly used for optical materials used in analysis devices that employ infrared waves as well as high power infrared lasers.
Fabrication and polishing
Our corporate strength is precision fabrication and polishing of fluorite and other optical glass.
