SUMMARY Measured values of the transmission of amorphous films as a function of the objective aperture and film thickness can be described by a single‐scattering theory for unfiltered and zero‐loss filtered images in the electron spectroscopic imaging mode of a transmission electron microscope. The theory can be applied to estimate the gain of contrast by zero‐loss filtering for specimen structures larger and smaller than the chromatic aberration disc.
