Abstract
It is demonstrated in this article that for an electromagnetic 2n−pole system with n=odd, the only existing symmetric aberration which could be used to correct the spherical aberrations of a round lens is the order of 2n−3. Thus, a 2n−pole corrector can only be used to cancel the aberration of round lenses of order 2n−3.This publication has 1 reference indexed in Scilit:
