Interaction between Chromatic and Spherical Aberration Corrections

The chromatic aberration remains or is even increased after using multipoles to correct spherical aberration. This energy spread degrades the spatial resolution in EMs’ imaging and also induces peaks broadening in an energy-loss spectrum, resulting in reduction of the amount of observable fine structure.
