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 50 pm resolution in annular dark field imaging mode and magnificationsof up
The study of mineralogical and petrographic samples using scanning electron microscopy is now routine in geological research. Similar to optical microscopy but with a much higher resolution, electron microscopy reveals detailed textural relationships between the mineral grains.

This discovery initiated the study of electron optics, and by 1931 German electrical engineers Max Knoll and Ernst Ruska had devised a two lens electron microscope that produced images of the electron source. In 1933 a primitive electron microscope was built that imaged a specimen rather than the electron source, and in 1935 Knoll produced a scanned image of a solid surface. The resolution of
