Scanning Electron Microscopes, or SEMs, function differently in that a narrow beam of electrons slowly passes over the object which you are examining. A magnified image is gradually revealed based on how electrons are reflected or absorbed by your specimen as the beam passes over it.
WebSEM stands for scanning electron microscope. The SEM is a microscope that uses electrons instead of light to form an image.
