We relied on technology accumulated through the manufacture of fluorite lenses for cameras to develop fluorescent materials with fluorite (CaF2) as the main component. This material offers a wealth of color variations, such as a fluorescent material that emits one of two colors depending on the light source.
Unlike organic fluorescent materials, regardless of the UV light exposure this material experiences almost no drop-off in emission intensity and its color remains constant even when under UV light for long periods.
These properties make the material suitable for use in many locations where conventional materials do not fare well.
Some of the many possible applications include ornaments and anti-counterfeiting. This artificial fluorite is truly Made In Japan, as all manufacturing process are done domestically.
