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.

Abstract: Method and apparatus for densitometry wherein a sample spot developed on a supporting medium is scanned by monochromatic light in a zigzag way, and at a predetermined point outside the spot in each scanning stroke the measured output is periodically sampled and stored so as to be subtracted from the measured output during the scanning stroke for correction of the base line of the measured output.

Abstract: Densitometer for quantitative determination of the content of a sample spot on a TLC plate or the like, wherein dualwavelength zigzag scanning is conducted on the spot. Light reflected and transmitted by the sample is received by photometers, and compensation based on Kubelka-Munk's theoretical equations is made on the photometer output so that the output is substantially proportional to the quantity of the substance in the spot being scanned.
