  2. Fluorescence microscope - Wikipedia

    en.wikipedia.org/wiki/Fluorescence_microscope

    [1] [2] "Fluorescence microscope" refers to any microscope that uses fluorescence to generate an image, whether it is a simple set up like an epifluorescence microscope or a more complicated design such as a confocal microscope, which uses optical sectioning to get better resolution of the fluorescence image. [3]

  3. Fluorescence imaging - Wikipedia

    en.wikipedia.org/wiki/Fluorescence_imaging

    Total internal reflection fluorescence microscopy: A microscopy technique that uses evanescent waves to selectively observe the fluorescence of a single molecule. [8] Light sheet fluorescence microscopy: A fluorescence microscopy technique that illuminates a thin slice of a sample at a perpendicular angle of examination. [9]

  4. Fluorescence - Wikipedia

    en.wikipedia.org/wiki/Fluorescence

    Fluorescence in the life sciences is used generally as a non-destructive way of tracking or analysis of biological molecules by means of the fluorescent emission at a specific frequency where there is no background from the excitation light, as relatively few cellular components are naturally fluorescent (called intrinsic or autofluorescence).

  5. Total internal reflection fluorescence microscope - Wikipedia

    en.wikipedia.org/wiki/Total_internal_reflection...

    A total internal reflection fluorescence microscope (TIRFM) is a type of microscope with which a thin region of a specimen, usually less than 200 nanometers can be observed. TIRFM is an imaging modality which uses the excitation of fluorescent cells in a thin optical specimen section that is supported on a glass slide.

  6. Fluorescence-lifetime imaging microscopy - Wikipedia

    en.wikipedia.org/wiki/Fluorescence-lifetime...

    Fluorescence lifetimes can be determined in the time domain by using a pulsed source. When a population of fluorophores is excited by an ultrashort or delta pulse of light, the time-resolved fluorescence will decay exponentially as described above. However, if the excitation pulse or detection response is wide, the measured fluorescence, d(t ...

  7. Bright-field microscopy - Wikipedia

    en.wikipedia.org/wiki/Bright-field_microscopy

    The light path of a bright-field microscope is extremely simple; no additional components are required beyond the normal light-microscope setup. The light path begins at the illuminator or the light source on the base of the microscope. Often a halogen lamp is used. The light travels through the objective lens into the ocular lens, through ...

  8. Light sheet fluorescence microscopy - Wikipedia

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

    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. In contrast to epifluorescence microscopy only a thin slice (usually a few hundred nanometers to a few micrometers) of the sample is illuminated ...

  9. Chlorophyll fluorescence - Wikipedia

    en.wikipedia.org/wiki/Chlorophyll_fluorescence

    ′: Minimal fluorescence (arbitrary units). Fluorescence level of light-adapted sample when all reaction centers of the photosystem II are open; it is lowered with respect to by non-photochemical quenching. ′: Maximal fluorescence (arbitrary units). Fluorescence level of light-adapted sample when a high intensity pulse has been applied.
