  • Patent number: 5483057
    Abstract: Apparatus for measuring the color of glass, particularly pieces of broken glass relies upon simultaneously measuring the glass transmission in different spectral regions. The glass pieces travel along a conveying path between a light source and a light sensor containing a plural number of optical filters and groups of photoelectric detectors. The groups of photoelectric detectors are disposed at an end face of respective substantially cylindrical tubes. Tube axes enclose an angle and intersect in a conveying plane defined by the conveying path. The optical filters have different spectral transmission regions. Optical lens systems are retained intermediate the respective groups of photoelectric detectors and an opposite end face of the respective tubes. Each optical lens system images the conveying plane at the associated group of photoelectric detectors.
