The evaluation of photographic plates in astronomical studies with the aid of special machines is considered, taking into account a machine which was especially designed for the evaluation of spectra. The machine was obtained for the Max-Planck-Institute for Astronomy in Heidelberg, Germany, from an American company. The machine has been automatized with the aid of a process computer. It can be employed as a comparator and a microdensitometer. When operated as a comparator, the machine makes it possible to determine the position of a spectral line with extremely high accuracy. Used as a microdensitometer, the described machine can scan a one-dimensional spectrum or a two-dimensional image area. The density values are either represented as a curve by means of a tape printer or they are recorded in digital form on magnetic tape.
