One of the option of spherical aberration correction in electron microscopy is the hexapole corrector. Although the principle of the corrector is described in literature quite elaborately the adjustment of the corrector, which is crucial for its functionality, is studied just briefly. The thesis is dedicated to the analytic analysis of parasitic aberrations and its influence on resolution of an image by the Eikonal method and aberration integrals. It is shown that off-axial shifts and tilts play the major role in parasitic aberrations. In the end the procedure of adjustment of the hexapole corrector for elimination of parasitic aberrations is described.
