Microscopy in electron diffraction apparatus.
A simple method was devised for observing electron micrographs as well as diffraction figures from a given object. A dielectric emulsion composed of paraffin and barium titanate acted here as an electrostatic lens when charged up with the incident electrons. Electron diffraction figures could immediately be observed from the same object as for microscopy when the lens was mechanically removed out of the electron path.
