Phase and amplitude contrast in electron microscopy of stained biological objects

For biological objects negatively stained with heavy atom material, electron microscope images show best contrast for image detail on the scale of 10–20 Å when a small objective aperture is used. In images taken under the optimum phase contrast imaging conditions of Scherzer, the required image deta...
