Electron microscope

Electron microscope

(Science: instrument) a microscope (device used to magnify small objects) which beams electrons at and through the object of interest instead of light beams. Instead of a glass lens to bend the light, a powerful magnet is used to bend the electron beam. The microscope can only be operated in a vacuum. This type of microscope provides the greatest resolution of extremely small details available and has been used to see individual atoms in an object or substance. 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.A modern microscope capable of magnifying images by thousands of times, which is done by firing electrons at the magnified specimen, where the resultant consequence of these electrons produces a false colour image for the microscope user to see.
