Abstract: An illuminator system for use in a spectrophotometer by which the mode of operation can be easily changed in a simple manner. To this end, means for shielding either of the beams emerged from respective monochromatic beam generators and means for shielding, when said first mentioned means is in the inoperative condition, the other of said beams that has passed through the sector diaphragm. By operating the above mentioned two means, the double wavelength, single beam spectrophotometer can be used as a single wavelength dual beam spectrophotometer and vice versa.
