A computational investigation on the simulation and design of symmetrical double polepiece magnetic electron lens using optimization by synthesis approach has been done. The field formula and its related axial functions requaired for synthesis design of the charged particle lens have been determined with aid of Simulation environment in Matlab. The objective focal properties of the double polepiece magnetic lenses with respect to the image space have been studied under the effect of the field parameters.
