Originally designed for photographic use, Kodak Wratten Filters have also become a popular choice for a wide variety of industrial applications.
Gelatine filters created by dissolving organic dyes in a gelatin material to achieve the desired spectral performance. The gelatin liquid and dye combination is then coated onto a supportive substrate until it has dried. After removal from the substrate, the film is coated with laquer for protection.
