Noun
transmission electron microscope (plural transmission electron microscopes)
A form of electron microscope in which a beam of electrons is transmitted through a thin layer of sample.
A transmission electron microscope can achieve better than 50 pm resolution citation and magnifications of up to about 10,000,000x whereas most light microscopes are limited by diffraction to about 200 nm resolution and useful magnifications below 2000x. Source: Internet
Ernst Ruska started development of the first electron microscope in 1931 which was the transmission electron microscope (TEM). Source: Internet
The major disadvantage of the transmission electron microscope is the need for extremely thin sections of the specimens, typically about 100 nanometers. Source: Internet
The spot size and the interaction volume are both large compared to the distances between atoms, so the resolution of the SEM is not high enough to image individual atoms, as is possible transmission electron microscope (TEM). Source: Internet
The transmission electron microscope uses electrostatic and electromagnetic lenses to control the electron beam and focus it to form an image. Source: Internet
The transmission electron microscope works on the same principle as an optical microscope but uses electrons in the place of light and electromagnets in the place of glass lenses. Source: Internet
