Aberrations in magnetically focused electron optics have been studied. By directly solving the equations of motion in imperfect fields, analytical formulas are derived for computing the axial and lateral deviations of electrons from their ideal position in perfect fields. The field curvature and distortion are deduced from the axial and lateral displacements of electrons with zero initial velocities. The reduction of distortion by increasing the magnetic-field intensity is discussed. A study of the resolution shows how results obtained with perfect fields apply and how the magnetic-field inhomogeneity induces asymmetric resolution loss in a direction depending on the on-axis field shape and intensity. Experimental results obtained by using a strong magnetic field of 5600 G are presented.
