Abstract. A diffraction system is proposed for spectrometric instruments. The system contains a cylindrical mirror in the spectrum formation plane and makes it possible to improve spectral resolution with no increase in mass and size of the system. Experiments carried out with the system reveal fine structure elements in green and blue lines of mercury bulb spectrum.
