  2. Scanning probe microscopy - Wikipedia

    en.wikipedia.org/wiki/Scanning_probe_microscopy

    Technology portal. v. t. e. Scanning probe microscopy (SPM) is a branch of microscopy that forms images of surfaces using a physical probe that scans the specimen. SPM was founded in 1981, with the invention of the scanning tunneling microscope, an instrument for imaging surfaces at the atomic level. The first successful scanning tunneling ...

    en.wikipedia.org/wiki/High-power_field

    The area provides a reference unit, for example in reference ranges for urine tests. [3]Used for grading of soft tissue tumors: Grading, usually on a scale of I to III, is based on the degree of differentiation, the average number of mitoses per high-power field, cellularity, pleomorphism, and an estimate of the extent of necrosis (presumably a reflection of rate of growth).

  4. 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 ...

    en.wikipedia.org/wiki/Objective_(optics)

    Two Leica oil immersion microscope objective lenses; left 100×, right 40×. The objective lens of a microscope is the one at the bottom near the sample. At its simplest, it is a very high-powered magnifying glass, with very short focal length. This is brought very close to the specimen being examined so that the light from the specimen comes ...

  6. Super-resolution microscopy - Wikipedia

    en.wikipedia.org/wiki/Super-resolution_microscopy

    Super-resolution microscopy is a series of techniques in optical microscopy that allow such images to have resolutions higher than those imposed by the diffraction limit, [1][2] which is due to the diffraction of light. [3] Super-resolution imaging techniques rely on the near-field (photon-tunneling microscopy [4] as well as those that use the ...

  8. Light field microscopy - Wikipedia

    en.wikipedia.org/wiki/Light_field_microscopy

    Light field microscopy (LFM) is a scanning-free 3-dimensional (3D) microscopic imaging method based on the theory of light field.This technique allows sub-second (~10 Hz) large volumetric imaging ([~0.1 to 1 mm] 3) with ~1 μm spatial resolution in the condition of weak scattering and semi-transparence, which has never been achieved by other methods.

  9. Electron microprobe - Wikipedia

    en.wikipedia.org/wiki/Electron_microprobe

    An electron microprobe (EMP), also known as an electron probe microanalyzer (EPMA) or electron micro probe analyzer (EMPA), is an analytical tool used to non-destructively determine the chemical composition of small volumes of solid materials. It works similarly to a scanning electron microscope: the sample is bombarded with an electron beam ...
