Optical Filter Glass is known for its selective absorption in the visible wavelength range. The Optical Filter Glasses appear to be colored if their filter effect lies within the visible spectrum.
Glass manufacturers using varieties of colorants with different concentrations and many types of base glasses have been developed to facilitate the development of an assortment of filters, some with extreme filter properties, in the largest possible spectral region.
Our color glass filters serve as broadband, bandpass, or long-wave pass filters. We offer a variety of Schott, Hoya or Chinese equivalent color glass filter covering from UV, visible to IR spectrum.
These filters are precision polished for demanding research or OEM applications.
