No single volume has been entirely devoted to the properties of
magnetic lenses, so far as I am aware, although of course all the
numerous textbooks on electron optics devote space to them. The
absence of such a volume, bringing together in formation about the
theory and practical design of these lenses, is surprising, for
their introduction some fifty years ago has created an entirely new
family of commercial instruments, ranging from the now traditional
transmission electron microscope, through the reflection and
transmission scanning microscopes, to co lumns for micromachining
and microlithography, not to mention the host of experi mental
devices not available commercially. It therefore seemed useful to
prepare an account of the various aspects of mag netic lens
studies. These divide naturally into the five chapters of this
book: the theoretical background, in which the optical behaviour is
described and formu lae given for the various aberration
coefficients; numerical methods for calculat ing the field
distribution and trajectory tracing; extensive discussion of the
paraxial optical properties and aberration coefficients of
practical lenses, il lustrated with curves from which numerical
information can be obtained; a comple mentary account of the
practical, engineering aspects of lens design, including permanent
magnet lenses and the various types of superconducting lenses; and
final ly, an up-to-date survey of several kinds of highly
unconventional magnetic lens, which may well change the appearance
of future electron optical instruments very considerably after they
cease to be unconventional."
