[Company strength]
Our core technology is optical lens polishing and forming. The performance of digital cameras and liquid crystal TVs has been improving, so the glass lenses used on the shooting device are required to have better performance and quality. We have applied our 50 years of production know-how and used using various measuring instruments to develop 8K- and 16K-compatible lenses. We developed ND filter films without using Cr in our optical thin film development work. Our original technology includes metal film forming such as TiN film, and protective film forming for metal dies. 


[Business description]
Our lines of business are optical lens polishing and forming, and polishing machine manufacturing and sales. We deal with various optical lenses.
