In this paper, several innovative designs of magnetic lenses were designed, a bipolar lens with different geometries, where the outer pole arm denoted by the symbol (L) was changed. With a current density (6 A / m²) and after its design, the geometric parameters were studied in terms of magnetic properties, then the optical properties were studied in terms of aberrations, i.e. the coefficient of spherical aberration and the coefficient of chromatic aberration. Which led to minor changes in some of them, while others did not make any changes
