Sharper Electron Microscope Pix
Close-up view of a special "phase plate" for improving the contrast
capability of transmission electron microscopes (TEM). The red beam symbolizes the
unscattered electron waves, which are shifted in phase by an electostatic field
leaking from the unshielded ring electrode. The blue beams symbolize the scattered
electron waves, which pass by the phase plate unchanged.
Schematic diagram of the TEM equipped with the phase plate.
