Optical Color Glass is gaining an ever-growing importance due to the progress of the instrument-making industry and the introduction of novel methods of research. Thus, the employment of color glass as optical filters not only expands significantly the potentials of diverse studies, but not infrequently provides the sole solution of the problem on hand.

Our colored glass filters serve as broadband, bandpass, or long wave pass filters. They absorb light of a specific color, while transmitting the balance. The thicker the filter, the more it will absorb. Colored glass filters are excellent for applications where a general spectral region must be separated or isolated from the region of interest. They are cost effective, very uniform over their entire aperture and easy to use.

Colored glass filters have found widespread use in application such as color correction, light balancing, control systems, studio and architectural lighting, color photocopier, signal systems on the railway, marine or motor vehicle transport etc. In research, optical filters are highly useful where it is a need to isolate a specific spectral region or, conversely, to exclude the light of a particular wavelength.

Each Optical Color Glass we sell, has a name (type) consisting of two or three letters and numbers. The first or the first two letters are the initial letters of color description, while the last one, letter “G” (same for all types), is the initial letter of word “glass”. All glasses of different types are grouped into 14 categories as follows

  • UVG - Ultra-Violet Glass
  • VG - Violet Glass
  • BG - Blue Glass
  • BGG - Blue-Green Glass
  • GG - Green Glass
  • YGG - Yellow-Green Glass
  • YG - Yellow Glass
  • OG - Orange Glass
  • RG - Red Glass
  • IRG - Infra-Red Glass
  • PG - Purple Glass
  • NG - Neutral Glass
