Contrast-transfer calculations indicate that Cc correction should be highly beneficial for high-resolution and energy-filtered transmission electron microscopy. A prototype of an electron optical system capable of correcting spherical and chromatic aberration has been used to verify these calculations. A strong improvement in resolution at an acceleration voltage of 80 kV has been measured. Our first Cc-corrected energy-filtered experiments examining a (LaAlO3)0.3(Sr2AlTaO6)0.7/LaCoO3 interface demonstrated a significant gain for the spatial resolution in elemental maps of La.
