    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.

    Abstract translation: 在商业色度计中，提供了一种用于将光从样品传导到几个光电管的装置，使得每个光电池几乎接收来自样品的相同照明。 通过使用不同的滤光片和光谱响应，色度计中使用光电信号的差异来提供高精度的色彩信息。 重要的是，这些信息不会被光的几何分布与不同的光电元件位置的差异所偏好。 导光装置包括一束内部光反射丝（轻纤维），其长丝单独地预先设置在束中的适当位置，以确保来自试样的每个区域的光分布在 与每个光电池相同的比例。
