Abstract

A colorimeter for measuring the color characteristics of an object, characterized in that a light guiding means is selectively operable to direct the light to a reference object and to an object to be sampled, so that light is reflected from said objects to light diffraction means that produce a spectrum of light received from each object, after which the spectral light from the diffraction means is directed against an operable shutter to select and allow only light from a chosen part of the spectrum of the reflected light enters a spectral light guiding means, which conduct the light of the chosen part of the spectrum to at least one transducer that of a comprehensible signal proportional to the intensity of the light received by the transducer (Machine-translation by Google Translate, not legally binding)
