This glass filter adjusts a sensitivity of CCD and CMOS image sensors (which are used in digital cameras such as cell phone cameras, security cameras, and vehicle cameras) to the spectral sensitivity of the human eye. It features a basic composition of fluorophosphate glass, so it has outstanding acid resistance, water resistance, and strength.


  • Digital single-lens reflex camera, compact camera, smartphone camera, cameras for automobiles, surveillance camera, etc.
  • Features

  • It contributes to excellent image quality with absorption type
  • It reduces ghosting and flares which have a bad influence on the image quality.
  • Incident angle dependence of spectral transmittance is small, and it balances the color of the entire picture.
  • It retains an integrated production system in a range from glass melting to forming/processing.
  • We respond to the customers’ requirements including technical support through the accumulated production technology know-how.
  • It also supports anti-reflection coating and UVIR cut film.
  • The variety of lineups are available so as to meet the spectral characteristies by the customers’ requirements.
