Scanning Electron Microscope Semitracks.
What is an SEM Examination? In 1938, von Ardenne added scan coils to a transmission electron microscope TEM, producing a scanning transmission electron microscope STEM. In 1942, Zworykin and his team developed the first scanning electron microscope to employ secondary electron detection.

Scanning Electron Microscope. The Scanning Electron Microscope SEM is an important tool for imaging material surface as well as for identifying chemical signatures. The UF Department of Geological Sciences has an SEM laboratory equipped with a Zeiss EVO MA10 and an EDAX EDS spectrometer.
Scanning tunneling microscope vs. scanning electron microscope.
The scanning electron microscope SEM is capable of imaging an object with a resolution of better than one nanometer. To put that in perspective, a meter is to the size of the earth as a nanometer is to the size of a marble.

SEM: Scanning Electron Microscope: Research Development: Hitachi.
SEM is one type of electron microscope. It is used for observing a physical object by irradiating an electron beam a narrow, focused stream of electrons onto the object by detecting, for example, secondary" electrons" emitted from the object and reflected" electrons" emitted when the direction of travel of the irradiating electron beam travelling within the object varies.
