    than can be seen when using the light microscope. In comparison to light microscopes electron microscopes provide a clearer picture‚ greater magnification and greater resolution. There are two types of electron microscope; the scanning electron microscope and the transmission electron microscope. Electron microscopes use electromagnetic and electrostatic lenses and some are able to magnify the specimen size by millions. The transmission electron microscope magnifies over 50‚000‚000X the resolution
