Electron microscope
Electron microscope is one of the most sophisticated microscopes known in science. Electron microscope uses electrostatic and electromagnetic lenses and by means of electrons illuminate an object, magnifying an image up to 2 million times while light microscopes only 2 thousand times. Electron microscope uses a wavelength of an electron called Broglie wavelength. By controlling the beam of electromagnetic radiation electron microscope makes it possible to focus it, producing an image of the greatest scale.
