A way to eliminate defocusing of charged particle beams in the dispersion plane in fringing fields of a sector deflector is proposed. The method is based on forming, by modification of the geometry of the deflector fringing field region, a non-monotonic distribution of the deflecting electrostatic field strength at the optic axis.
