Abstract: In a commercial colorimeter, a device is provided for conducting light from a specimen to several photocells in such a way that each photocell receives geometrically the same illumination from the specimen. By using different filters and spectral responses, differences in photocell signal are used in the colorimeter to provide chromatic information of high precision. It is important that this information not be biased by differences in geometric distribution of light to the different photocell positions. The light-conducting device comprises a bundle of internal light reflecting filaments (light fibers), the filaments of which are individually pre-set in place in the bundle in such a manner as to insure that light from each area of the specimen is distributed in the same proportion to each photocell.
