Abstract: The color contribution of a lens has been defined in terms of its transmittance density at 400 and 700 mμ. It is proposed that the difference in the densities at these two wavelengths be held to 0.05 ± .03 for motion picture camera lenses; 0.05 ± .05 for other camera lenses. To prevent the curve from being too highly inflected between these two points an additional requirement is that the minimum density between 400 and 700 mμ differ from the density at 700 mμ by no more than 0.04 density units. It has been found convenient to describe quantitatively the glass absorption by a term called “color index.” A simple method of determining the combined effect of glass absorption and surface coating is outlined.
