Abstract: High-resolution observation of a large field of view with a high quality detector is important for single particle analysis or in-situ experiments. Consequently, evaluation of aberrations that depend on position in the field of view, (off-axial aberrations) is required. We report the experimental measurement of off-axial aberrations including higher order components in several optical conditions together with the corresponding off-axial phase maps.
