Electron microscope - Wikipedia
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. As the wavelength of an electron can be up to 100,0… See more

- An electron microscope is a type of microscope that uses a beam of accelerated electrons as a source of illumination. It has a higher resolving power than light microscopes and can reveal the structure of smaller objects, as the wavelength of an electron can be up to 100,000 times shorter than that of visible light photons1. Electron microscopes were invented in Germany in the 1930s2. A beam of electrons is sent towards the specimen, and those that pass through are detected and used to form an image of the specimen at a magnification of about 500,000 times2.Learn more:✕This summary was generated using AI based on multiple online sources.

en.wikipedia.org/wiki/Electron_microscopeElectron microscopes were invented in Germany in the 1930s. A beam of electrons is sent towards the specimen - some electrons are reflected, while some pass through. Those that pass through are detected and used to form an image of the specimen at a magnification of about 500,000 times.

Scanning electron microscope - Wikipedia
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. The electron beam is scanned in a raster scan pattern, and the po…

- The field of microscopy (optical microscopy) dates back to at least the 17th-century. Earlier microscopes, single lens magnifying glasses with limited magnification, date at least as far back as the wide spread use of lenses in eyeglasses in the 13th century but more advanced compound microscopes first appeared in Europe around 1620 The earliest pr...
