Several types of fast digitization devices consisting of CCD cameras and frame grabbers have appeared and been implemented in astronomical practice during the last decade. Nevertheless, various types of classical scanning devices are still used for precise digitization of astronomical images and spectrograms. Among them, a new type of microphotometer with a rotating slit (UMF) was adjusted and installed at the Ondřejov Observatory (Zicha et al. 1992). Technical parameters of the device are as follows:
