ABSTRACT:
A colorimeter in which a beam dividing assembly is supported on a movable carriage intermediate the sample and reference detectors. The assembly separates the incoming collimated light into a sample beam and a reference beam. The movement of the carriage toward or away from the sample produces a decrease or increase in the intensity of the light illuminating the sample and a corresponding increase or decrease in the intensity of the light at the reference detector. The arrangement is such that the apparatus may be readily adjusted to obtain accurate colorimeter readings even for samples having abnormally high or low density characteristics.
