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

A microscope that produces images of extremely small objects by using beams of electrons rather than visible light. Since electrons have a much shorter wavelength than light, the use of electron beams rather than light beams can resolve much finer structural details in the sample. Electrons are beamed at the sample and focused by magnets; a detector then converts the refracted or reflected beams into a black and white image. Powerful electron microscopes can create accurate images of objects as small as individual molecules. See also scanning electron microscope.

Noun

1.

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"
