Abstract
Previous authors have described the imaging properties of magnetic lenses for the electron microscope and have calculated the best lens performance with existing magnetic materials. The best lens performance can only be obtained if the design of the magnetic circuit is correct. Suitable design curves are given, based upon flux measurements in models. The effect of iron saturation is briefly described.Keywords
