Results of research of the possibility of the use of bimorph mirrors DM2-100-31 for operation of the tip-tilt of wave front at giving voltage on an external ring of operating electrodes are presented. The static characteristic of a mirror operated on inclinations is measured at various light apertures. The range of linear change slope of angles of the mirror depending on the pressure on operating electrodes is determined. It is shown that the use of the bimorph mirror DM2-100-31 in the adaptive optical system of the Big solar vacuum telescope will allow to compensate the tip-tilt of the wave front on the aperture of the telescope in a range ± 4.8 angular seconds.
