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 ...

3. Serial block-face scanning electron microscopy - Wikipedia

   en.wikipedia.org/wiki/Serial_block-face_scanning...

   The EyeWire project harnesses human computation in a game to trace neurons through images of a volume of retina obtained using serial block-face scanning electron microscopy. [ 7 ] Many different samples can be prepared for serial block-face scanning electron microscopy and the ultramicrotome is able to cut many materials, therefore this ...

4. Scanning transmission electron microscopy - Wikipedia

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

   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. However, unlike CTEM, in STEM the electron beam is focused ...

5. Electron microscope - Wikipedia

   en.wikipedia.org/wiki/Electron_microscope

   A transmission electron microscope from 2002 An image of an ant in a scanning 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 ...

6. Microscopy - Wikipedia

   en.wikipedia.org/wiki/Microscopy

   Scanning electron microscope image of pollen (false colors) Microscopic examination in a biochemical laboratory. Microscopy is the technical field of using microscopes to view objects and areas of objects that cannot be seen with the naked eye (objects that are not within the resolution range of the normal eye). [1]

7. High-resolution transmission electron microscopy - Wikipedia

   en.wikipedia.org/wiki/High-resolution...

   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, nanoparticles and sp 2 -bonded carbon (e.g ...

8. Electron tomography - Wikipedia

   en.wikipedia.org/wiki/Electron_tomography

   Electron tomography (ET) is a tomography technique for obtaining detailed 3D structures [1] of sub-cellular, macro-molecular, or materials specimens. Electron tomography is an extension of traditional transmission electron microscopy and uses a transmission electron microscope to collect the data.

9. Annular dark-field imaging - Wikipedia

   en.wikipedia.org/wiki/Annular_dark-field_imaging

   Annular dark-field imaging is a method of mapping samples in a scanning transmission electron microscope (STEM). These images are formed by collecting scattered electrons with an annular dark-field detector. [1] Conventional TEM dark-field imaging uses an objective aperture to only collect scattered electrons that pass through.
