electron microscope

n.
Any of a class of microscopes that use electrons rather than visible light to produce magnified images, especially of objects having dimensions smaller than the wavelengths of visible light, with linear magnification approaching or exceeding a million (106).

electron microscope

n
(General Physics) a powerful type of microscope that uses electrons, rather than light, and electron lenses to produce a magnified image

elec′tron mi`croscope


n.
a microscope of extremely high power that uses beams of electrons focused by magnetic lenses instead of rays of light, the magnified image being formed on a fluorescent screen or recorded on a photographic plate.
[1930–35]

electron microscope

An instrument that uses a beam of electrons to view objects that are too small to be seen with an ordinary microscope. As the electrons hit the object being viewed, other electrons are knocked loose from its surface and are picked up by a detector that converts them into a black and white image.
ThesaurusAntonymsRelated WordsSynonymsLegend:
Noun1.electron microscope - a microscope that is similar in purpose to a light microscope but achieves much greater resolving power by using a parallel beam of electrons to illuminate the object instead of a beam of light
electron gun - the electrode that is the source of electrons in a cathode-ray tube or electron microscope; consists of a cathode that emits a stream of electrons and the electrostatic or electromagnetic apparatus that focuses it
field-emission microscope - electron microscope used to observe the surface structure of a solid
microscope - magnifier of the image of small objects; "the invention of the microscope led to the discovery of the cell"
