Abstract
Quadruple lenses 30, 31 and 32 and sextupole lenses 40, 41, 42, and 43 are interposed between a energy-dispersing device 17 and an electron imaging device 50 in an energy-selected electron imaging filter. The energy-dispersing device produces a focussed spectrum 21 of electron energies in the plane of an energy-selecting slit 20, and the quadrupole and sextupole lenses transform the spectrum into an energy-selecting slit may also be either removed or opened wide, and the quadrupole lenses may be refocussed, so that the electron imaging device directly observes a magnified spectrum of the electron energies.
