The Electron Microscope (EM) is a type of scientific microscope that uses a beam of electrons to create an image of the target. Electron Microscopes function the same way as other types of microscopes, except they use electrons instead of light to create an image of specimen and gather information about its structure. Electron Microscopes were developed due to the limitations of light microscopes, which are limited by the physics of light to 500x or 1000x magnification and a resolution of 0.2 micrometers. It was developed by Max Knoll and Ernst Ruska in Germany in 1931.
