electron microscope
an instrument that focuses a beam of electrons on an object, using electric or magnetic fields, to form an enlarged image of the object on a fluorescent screen, photographic plate, or cathode-ray tube; specif., such an instrument in which the beam of electrons passes directly through an extremely thin object and forms a two-dimensional image: it is much more powerful than any optical microscope: cf. SCANNING ELECTRON MICROSCOPE
