Unconventional Lens Design

  • Chapter
Magnetic Electron Lenses

Part of the book series: Topics in Current Physics ((TCPHY,volume 18))

Abstract

Conventional magnetic electron lenses have evolved to their present highly developed state under the pressing requirements of high resolution transmission electron microscopy. However, recent changes in the emphasis of electron microscopy towards quantitative analysis at high resolution have made it desirable to undertake a reappraisal of the basic design of magnetic electron lenses. This is timely and relevant now that improved numerical methods are available for calculating the electron optical performance of unconventional lens designs. Moreover, technological developments in electron field-emission sources and superconducting lens elements make it desirable to reconsider the whole basis of the subject. The present chapter is, therefore, chiefly concerned with opening up new ways of thinking about electron lenses and realising them in practice in the light of the information presented in the preceding chapters.
