Automatic modulating installation for obtaining of optical spectra of metals and compounds is described. The installation enables to obtain, besides the reflectivity coefficient spectra, the optical thermo-modulation spectra and wave-length modulation ones. Spectral interval, which depends on the used monochromator and detectors, is 0,5-6 eV. The optical and electronic schemes of the installation are given. Some samples of modulation spectra are presented.
