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.

Conventional scanning electron microscopy depends on the emission of secondary electrons from the surface of a specimen. Because of its great depth of focus, a scanning electron microscope is the EM analog of a stereo light microscope.
