/əˌlɛkˌtrɑn ˈmaɪkrəˌskoʊp/,

/iˌlɛkˌtrɑn ˈmaɪkrəˌskoʊp/

Origin: Formed within English, by compounding; modelled on a German lexical item. Etymons: electron n.², microscope n.

Etymology: < electron n.² + microscope n., after German Elektronenmikroskop (E. Brüche 1932, in Naturwissenschaften 15 Jan. 49).

A microscope which employs a beam of electrons to illuminate the sample, focusing the reflected or transmitted electrons using electron lenses to produce an image with much greater magnification and resolution than is possible with light.scanning electron microscope, transmission electron microscope: see the first element.
