We have imprint technology that forms fine structures on glass surfaces.
Using ultra-high precision molds, it is possible to directly form nano- and micro-order resin microstructures on various glass substrates with high accuracy. Additionally, by adopting original optical resins, it is possible to meet various optical characteristics and reliability standards.
