Scanning electron microscope - Wikipedia
https://en.wikipedia.org/wiki/Scanning_electron_microscope
WEBA scanning electron microscope (SEM) is a type of electron microscope that produces images of a sample by scanning the surface with a focused beam of electrons. The electrons interact with atoms in the sample, producing various signals that contain information about the surface topography and composition of the sample.
