Abstract. A brief description of design of spectrographs, located stationary on the Nasmyth focus platforms of the 6-meter telescope. The spectrographs with crossed dispersion NES and Lynx (where the crossed dispersion is provided by diffraction gratings) are considered, as well as the medium-resolution spectrograph (the crossed dispersion is obtained with a prism) and the classical diffraction spectrograph (MSS). These spectrographs can be relatively quickly prepared to observations as for the main scientific program and as a backup device. To measure circular and linear polarization in stellar spectra it is necessary to accumulate a large signal to ensure sufficient spectral resolution. The necessity of calibration to be to performed to account for instrumental effects is noted.
Keywords: large telescope, spectrograph, polarization analyzer, CCD, Stokes parameters, spectra of stars
