Schott Glass Absorbing ND Filters

Schott glass absorbing ND, solid glass, filters operate through a process of either ionic absorption by inorganic material dispersed uniformly throughout the filter or by way of absorptive scattering crystallites formed within the glass. These Schott glass absorbing ND, solid glass, filters are used in such areas as photography, colorimetry, contrast enhancement, color conversion and a variety of other scientific and general purposes uses.
