Color Glass Filters are made from optically polished highest quality Schott colored optical glass. The spectral properties of these color filters are uniform over the entire aperture and independent of angle of incidence. Color Glass Filters can be used alone or in conjunction with monochromators or interference filters to isolate various spectral regions.
