Everything about Electron microscope

Type of microscope with electrons as a source of illumination

An electron microscope is a microscope that uses a beam of electrons as a source of "illumination". It uses electron optics that are analogous to the glass lenses of an optical light microscope to control the electron beam, for instance focusing it to produce magnified images or electron diffraction patterns. As the wavelength of an electron can be more than 100,000 times smaller than that of visible light, electron microscopes have a much higher resolution of about 0.1 nm, which compares to about 200 nm for light microscopes. Electron microscope may refer to:Transmission electron microscope (TEM) where swift electrons go through a thin sample Scanning transmission electron microscope (STEM) which is similar to TEM with a scanned electron probe Scanning electron microscope (SEM) which is similar to STEM, but with thick samples Electron microprobe similar to a SEM, but more for chemical analysis Low-energy electron microscope (LEEM), used to image surfaces Photoemission electron microscope (PEEM) which is similar to LEEM using electrons emitted from surfaces by photons Wikipedia →

📖 Definitions

Noun Any of several forms of microscope that use a beam of electrons, rather than one of light, and thus has a much greater resolving power.
