Iron-free objective lenses II
Published online by Cambridge University Press: 15 March 2002
Abstract
The main factors limit the field of the magnetic lenses are the current density σ and the accelerating voltage Vr. Optical properties such as chromatic and spherical aberration have been studied in terms of σ and Vr. Values of the other aberration coefficients for the optimum lens size corresponding to the desired minimum aberration are estimated.
