The number of pixels or resolution elements in STEM images has frequently been relatively low (< 105) and in many images only a few gray levels can be distinguished. This is surprising considering the high brightness of the electron sources used in most cases, and the high contrast typically present in STEM images. While it is technologically expensive to match the several million resolution elements resolved in high quality TEM images, it is shown here that it is relatively straightforward to produce STEM images containing at least a million resolution elements.
