Abstract
The inverse design ol asymmetrical double polepiece magnetic
elcctron lenses has beei investigated with the aid ofan axial magnetic field
distribution representetl by a well-known malhematical field modcl in
electron optics. The influence ofthe magnetic field model parameters on
the focal propenies and the polepieces profile ot asymmEtrical magnetic
electron lenses has becn taken into account. 'fhe mr.)st effective parameters
on the design configuration are the two halfuidths ol the axial magnetic
field distrib"ution. Tie results have shown that the polepieces of various
asymmetrical double polepiece magnetic lcnses can be. reconstructed
