It achieves stable quality through a micro processing technology with high precision, and can be used for the applications which require high reliability due to a glass product. Additionally, it offers a wide variety of solutions on the basis of liquid crystal material technology, ultra-high-precision processing technology, and integrated technology.


  • Optical pickup for CD/DVD/Blu-ray
  • Optical imaging device
  • Optical communication device
  • The world’s first distinctive optical element which integrates the three technologies such as glass substrate technology, organic thin film technology, and optical design technology. With the distinctive technology which piles up the organic thin film functional material on the glass substrate in layers, accumulate various functions in which conventionally individual parts have assumed into one element compactly. Additionally, supports CD/DVD/Blu-Ray with one element, while combining the technologies which synthesize laser light with a different wavelength, and bends only the selected light.


  • The element controls light as intended by using holograms or gratings Holograms or gratings are precisely fabricated on the glass surface or inner space between glass substrates.
  • Customized size-designing is possible.
  • High efficient polarization filter is achieved.
  • Customized optical beam control (dot-beams, uniform illumination, etc.) is possible.
  • Product group of planar optical devices

    As for the main products group, we have products such as micro lens array, transmission grating, and wave plate element.
