Color Glass Filters

Color glass filters made from optically polished Schott colored optical glass, such as UG5, UG11, NG9 and KG5. The spectral properties are uniform over the entire aperture and independent of angle of incidence. They can be used alone or in conjunction with monochromators or interference filters to isolate various spectral regions. Available as round and square filters, e.g. 25.4 mm and 50.8 mm sizes, uncoated or AR coated.
