Q. What are KODAK Wratten Filters?
A. Optical filters consist mainly of colorants dissolved in gelatin. Most Kodak filters are made by dissolving suitable organic dyes in liquid gelatin and coating the proper amount of the solution onto prepared glass. After the coating is dry, the gelatin film is stripped from the support material. Each gelatin filter is standardized for spectral transmittance and total transmittance by special instruments which apply an optical form of limit gauge to these characteristics.
The most complete line of Kodak filters for photographic uses is available in the form of gelatin films. Prepared in the manner described above, gelatin filters have a thickness of 0.1 mm plus or minus 0.01 mm. Because of their uniform thickness, gelatin filters have excellent optical quality and are suitable for precise work in which little effect on definition and no increase in length of the optical path can be tolerated.
