The solution of the electrode and pole piece reconstruction problem is given. The axial potential or flux density distribution is sought in the form of a simple curve with a continuous second derivative. The reconstruction procedure then is extremely simple and quite accurate. As an example the electrode system for an optimized electrostatic lens is shown.
