An electron microscope is a microscope that uses a beam of accelerated electrons as a source of illumination. As the wavelength of an electron can be up to 100,000 times shorter than that of visible light photons, electron microscopes have a higher resolving power than light microscopes and can reveal the structure of smaller objects. A scanning transmission electron microscope has achieved better than 50pm resolution in annular dark-field imaging mode[1] and magnifications of up to about 10,000,000x whereas most light microscopes are limited by diffraction to about 200nm resolution and useful magnifications below 2000x.
