The construction and the operation of a photometer for measuring photographic plates is described. It works fully automatically, controlled by a computer, assigns the comparison spectrum and delivers a microphotometer trace on a linear frequency scale. All the information present on the photographic plate is extracted without the addition of noise to the data. The precision in the determination of the line positions is 0.4 μm.
