Schematic optical diagram of the Bausch & Lomb Spectronic 20 Colorimeter. As shown in the schematic optical diagram (see left), polychromatic light from a source in the system passes through lenses which are reflected and dispersed by the diffraction grating to restrict the range of light wavelengths. This restricted range of wavelengths is ...
