Company information

In the 21st century, it is said that the development of the information society will progress in leaps and bounds, and as part of this the miniaturization of semiconductors is important. A single crystal, high resolution lens is used as a key component of leading model of the stepper that manufactures fine semiconductors. We have a strong reputation for the manufacture of high purity calcium fluoride as lens materials, and the top market share in the industry.
In addition to semiconductor manufacturing, we have a strong engagement with many customers requiring lens materials for the development of digital cameras, security cameras, TV cameras, telescopes etc. Further, the need for our high-purity products is increasing as lens materials with strong resistance and high transmittance are needed for laser light sources and scintillators.
Since  the company was formed, we have  focused on development of high-purity inorganic chemical materials for use in the fields such as phosphor materials through to  optical lenses. We will continue to further develop our unique competitive advantage of  technology while harmonizing with the environment. As a company we wish to contribute to the advancement of society by providing products that are trusted by our customers.
I would like to ask for further support in the future.
