  2. Scanning electron microscope - Wikipedia

    en.wikipedia.org/wiki/Scanning_electron_microscope

    An account of the early history of scanning electron microscopy has been presented by McMullan. [2] [3] Although Max Knoll produced a photo with a 50 mm object-field-width showing channeling contrast by the use of an electron beam scanner, [4] it was Manfred von Ardenne who in 1937 invented [5] a microscope with high resolution by scanning a very small raster with a demagnified and finely ...

    en.wikipedia.org/wiki/TESCAN

    The history of electron microscope production in Czechoslovakia dates back to the 1950s when a team led by Armin Delong in Brno started to produce electron microscopes. One of the first successful microscopes was the Tesla BS 242 model, which won a gold medal at the EXPO 1958. During its 30-year existence, Tesla produced over 3,000 different ...

    www.fei.com. FEI Company (Field Electron and Ion Company) was an American company that designed, manufactured, and supported microscope technology. Headquartered in Hillsboro, Oregon, FEI had over 2,800 employees and sales and service operations in more than 50 countries around the world. Formerly listed on the NASDAQ, it is now a subsidiary of ...

  5. Electron-beam technology - Wikipedia

    en.wikipedia.org/wiki/Electron-beam_technology

    Electron-beam machining is a process in which high-velocity electrons are concentrated into a narrow beam with a very high planar power density. The beam cross-section is then focused and directed toward the work piece, creating heat and vaporizing the material. Electron-beam machining can be used to accurately cut or bore a wide variety of metals.

  6. Scanning transmission electron microscopy - Wikipedia

    en.wikipedia.org/wiki/Scanning_transmission...

    Inside the aberration corrector (hexapole -hexapole type) A scanning transmission electron microscope (STEM) is a type of transmission electron microscope (TEM). Pronunciation is [stɛm] or [ɛsti:i:ɛm]. As with a conventional transmission electron microscope (CTEM), images are formed by electrons passing through a sufficiently thin specimen.

  7. Environmental scanning electron microscope - Wikipedia

    en.wikipedia.org/wiki/Environmental_scanning...

    The environmental scanning electron microscope (ESEM) is a scanning electron microscope (SEM) that allows for the option of collecting electron micrographs of specimens that are wet, uncoated, or both by allowing for a gaseous environment in the specimen chamber. Although there were earlier successes at viewing wet specimens in internal ...

  8. Ultrafast scanning electron microscopy - Wikipedia

    en.wikipedia.org/wiki/Ultrafast_scanning...

    Ultrafast scanning electron microscopy (UFSEM) combines two microscopic modalities, Pump-probe microscopy and Scanning electron microscope, to gather temporal and spatial resolution phenomena. The technique uses ultrashort laser pulses for pump excitation of the material and the sample response will be detected by an Everhart-Thornley detector.

  9. Scanning tunneling microscope - Wikipedia

    en.wikipedia.org/wiki/Scanning_tunneling_microscope

    A scanning tunneling microscope (STM) is a type of scanning probe microscope used for imaging surfaces at the atomic level. Its development in 1981 earned its inventors, Gerd Binnig and Heinrich Rohrer, then at IBM Zürich, the Nobel Prize in Physics in 1986. [1][2][3] STM senses the surface by using an extremely sharp conducting tip that can ...
