    en.wikipedia.org/wiki/Scanning_electron_microscope

    A scanning electron microscope (SEM) is a type of electron microscope that produces images of a sample by scanning the surface with a focused beam of electrons. The electrons interact with atoms in the sample, producing various signals that contain information about the surface topography and composition of the sample.

    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.

    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 ...

    en.wikipedia.org/wiki/Electron_microscope

    Electron microscope. An electron microscope is a microscope that uses a beam of electrons as a source of illumination. They use electron optics that are analogous to the glass lenses of an optical light microscope to control the electron beam, for instance focusing them to produce magnified images or electron diffraction patterns.

    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 ...

    High-resolution image of magnesium sample. High-resolution transmission electron microscopy is an imaging mode of specialized transmission electron microscopes that allows for direct imaging of the atomic structure of samples. [1][2] It is a powerful tool to study properties of materials on the atomic scale, such as semiconductors, metals ...
