cant chromatic aberration and provide a sharp image only at exactly one energy of the electrons; therefore, inelastic scattered electrons blur the image.
In contrast to elastic scattering, inelastic scattered electrons have lost energy.
In view of the high-resolution imaging, the inelastic scattered electrons lead to chromatic aberration in the image, whereby the quality of the images will be reduced.
ngerprint" for the elements in the specimen and therefore the energy distribution of the inelastic scattered electron may also be used for elemental analysis of the specimen.
largest portion of the inelastic scattered electrons are spread over a much larger angle as compared to the elastic scattered electrons, and are stopped at the objective lens diaphragm.
