Abstract
In a color measuring spectrometer employing a reflecting grating and a linear array of photodetectors for measuring different components of a spectrum, the width of the photodetectors varies throughout the length of the array. The width of each photodetector is selected so that each photodetector detects the same bandwidth interval measured in wavelengths.
