scanning electron microscope
a device in which the specimen is examined point by point directly in a moving electron beam, and electrons reflected by the specimen are used to form a magnified, three-dimensional image on a television screen. Abbreviation: SEM
A scanning electron microscope (SEM) is a type of electron microscope that
produces images of a sample by scanning it with a focused beam of electrons.
