  2. Optical microscope - Wikipedia

    en.wikipedia.org/wiki/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.

  3. Microscopy - Wikipedia

    en.wikipedia.org/wiki/Microscopy

    Stereo microscope. Optical or light microscopy involves passing visible light transmitted through or reflected from the sample through a single lens or multiple lenses to allow a magnified view of the sample. [11] The resulting image can be detected directly by the eye, imaged on a photographic plate, or captured digitally. The single lens with ...

  4. Bright-field microscopy - Wikipedia

    en.wikipedia.org/wiki/Bright-field_microscopy

    Bright-field microscopy is the simplest of a range of techniques used for illumination of samples in light microscopes, and its simplicity makes it a popular technique. The typical appearance of a bright-field microscopy image is a dark sample on a bright background, hence the name.

  5. Confocal microscopy - Wikipedia

    en.wikipedia.org/wiki/Confocal_microscopy

    Fluorescence and confocal microscopes operating principle. Confocal microscopy, most frequently confocal laser scanning microscopy (CLSM) or laser scanning confocal microscopy (LSCM), is an optical imaging technique for increasing optical resolution and contrast of a micrograph by means of using a spatial pinhole to block out-of-focus light in image formation. [1]

  6. Light sheet fluorescence microscopy - Wikipedia

    en.wikipedia.org/wiki/Light_sheet_fluorescence...

    The principle setup of a light sheet fluorescence microscope. Light sheet fluorescence microscopy (LSFM) is a fluorescence microscopy technique with an intermediate-to-high [1] optical resolution, but good optical sectioning capabilities and high speed.

  7. Phase-contrast microscopy - Wikipedia

    en.wikipedia.org/wiki/Phase-contrast_microscopy

    Phase-contrast microscopy (PCM) is an optical microscopy technique that converts phase shifts in light passing through a transparent specimen to brightness changes in the image. Phase shifts themselves are invisible, but become visible when shown as brightness variations.

  8. Stereo microscope - Wikipedia

    en.wikipedia.org/wiki/Stereo_microscope

    The stereo, stereoscopic or dissecting microscope is an optical microscope variant designed for low magnification observation of a sample, typically using light reflected from the surface of an object rather than transmitted through it. The instrument uses two separate optical paths with two objectives and eyepieces to provide slightly ...

  9. 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.
