From the dawn of the optical thin film to the present day, we have been steadily working as a manufacturer specializing in optical thin films. We have many technologies and know-how about thin film design, the film formation process and film thickness control. Based on these technologies, we are contributing to society as the world's leading optical thin film manufacturer. Since our foundation, we have gained much experience over a wide wavelength range from UV to IR and a wide range of optical applications, so we can respond to every need. We will continue to provide products that satisfy everyone through advanced thin film technology and innovative products.
