Colored Filter Glass Pricing Tool for Custom Sizes

Color glass optical filters operate through absorption rather than the application of coatings. Many types of color glass filters are available including bandpass, shortpass, longpass, neutral density, heat absorbing, and multiband filters.
Please enter your required specifications here:
Glass Type
  • BG - Blue, blue-green, and multiband
  • GG - Colorless to yellow, IR transmitting
  • KG - Colorless glasses, high VIS transmission and IR absorption
  • NG - Neutral density glasses with uniform attenuation in VIS
  • OG - Orange glasses, IR transmitting
  • RG - Red and black glasses, blocking VIS, IR transmitting
  • UG - Black and blue glasses, UV transmitting
  • VG - Green glasses
  • WG - Colorless glasses w/ different UV cut-offs, transmitting in VIS and IR
