Types of Electron Microscopes

Types of Electron Microscopes. Electron microscopes use a beam of electrons rather than visible light to illuminate the sample. They focus the electron beam using electromagnetic coils instead of glass lenses (as a light microscope does) because electrons can’t pass through glass.
