The Scanning Electron Microscope developed by professor Dr. Charles Oatlev with the assistance of graduate students in the 1950s, are one of the three types of electron microscopes (EM). Electron microscopes utilize the same basic principles as light microscopes , but focus beams of energetic electrons rather than photons, to magnify an object. The electron beam of a scanning electron microscope interacts with atoms at different depths within the sample to produce different signals including secondary electrons, back-scattered electrons, and characteristic X-rays.

This represents another whole family of microscopes because it examines objects by scanning the surface with a fine electron beam as opposed to passing it through the sample. The beam are reflected and scattered and a 3d image is built up from this data. Since then, a range of electron microscope techniques have been developed.
