Definition of transmission electron microscope in English:

transmission electron microscope


  • A form of electron microscope in which an image is derived from electrons which have passed through the specimen, in particular one in which the whole image is formed at once rather than by scanning.

    • ‘A transmission electron microscope image is an in-focus projection through the specimen.’
    • ‘Ultrathin sections were made with an ultramicrotome; these were stained with uranyl acetate and lead citrate and examined under a transmission electron microscope.’
    • ‘The transmission electron microscope utilizes a high-energy electron beam generated by a heated filament which is focused onto a specimen by means of a condenser lens.’
    • ‘In addition to these tip links a second class of filamentous structures was identified in the scanning and transmission electron microscope: the side-to-side links.’
    • ‘All this occurred at furnace temperatures within a custom-designed transmission electron microscope.’
