  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 ...

    Area per high-power field for some microscope types: Olympus BX50, BX40 or BH2 or AO: 0.096 mm 2 [1] AO with 10x eyepiece: 0.12 mm 2 [1] Olympus with 10x eyepiece: 0.16 mm 2 [1] Nikon Eclipse E400 with 10x eyepiece and 40x objective: 0.25mm 2 [2] Leitz Ortholux: 0.27 mm 2 [1] Leitz Diaplan: 0.31 mm 2 [1]

  4. Objective (optics) - Wikipedia

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

    One of the most important properties of microscope objectives is their magnification.The magnification typically ranges from 4× to 100×. It is combined with the magnification of the eyepiece to determine the overall magnification of the microscope; a 4× objective with a 10× eyepiece produces an image that is 40 times the size of the object.

  5. Optical microscope - Wikipedia

    en.wikipedia.org/wiki/Optical_microscope

    Optical microscope. The optical microscope, also referred to as a light microscope, is a type of microscope that commonly uses visible light and a system of lenses to generate magnified images of small objects. Optical microscopes are the oldest design of microscope and were possibly invented in their present compound form in the 17th century.

  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 ...

  7. 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 ...
