الخواص البصرية الشيئية لعدسة مغناطيسية الكترونية متناظرة ثنائية القطب مشبعة مغناطيسيا

A depends on Synthesis method (inverse design method) and use two well - known mathematical models in electron optics such as Glaser’s Bell-shaped model and Grivet-Lenz model, have been used magnetic pole piece reconstruction produces from axial magnetic flux density distribution for this models to design symmetrical double pole piece magnetic electron lens and then saturation this lens magnetically to calculate the optical objective properties such as objective focal length, spherical aberration and chromatic aberration as well as resolving power for designing lenses.
