• The ion optical trajectories in the entrance and exit fringing fields of an electrostatic hexapole lens are calculated in a third order approximation. The potential distribution in a vicinity of the boundary is assumed to be a function which changes gradually along the center line but keeps the symmetrical and anti-symmetrical natures similar to the ideal hexapole lens. The influence of the extended. fringing field is reduced to a small bend and shift of the ion trajectory for the ideal field with a sharp cutoff boundary. The results of calculation are described in a transfer matrix representation.
