A fluorescence microscope is an optical microscope that uses fluorescence and phosphorescence instead of, or in addition to, scattering, reflection, and attenuation or absorption, to study the properties of organic or inorganic substances. "Fluorescence microscope" refers to any microscope... "Fluorescence microscope" refers to any microscope that uses fluorescence to generate an image, whether it is a simple set up like an epifluorescence microscope … British scientist Sir George G. Stokes first described fluorescence in 1852 and was responsible for coining the term when he observed that the mineral A substance is said to be fluorescent when it absorbs the energy of invisible shorter wavelength radiation (such as UV light) and emits longer wavelength radiation of visible light (such as green or red light). The fluorescence microscope provides enhanced contrast, single protein specificity andsingle molecule sensitivity.Progressin the This technique is most commonly used to determine the amount of some specific substance, such as DNA, in some particular area of a cell. Fluorescence microscopy combines the magnifying properties of the light microscope with fluorescence technology that allows the excitation of- and detection of emissions from- fluorophores - fluorescent chemical compounds. A fluorescence microscope, on the other hand, uses a much higher intensity light source which excites a fluorescent species in a sample of interest. This means that the molecule can absorb and emit photons, or particles of light, of different wavelengths. Fluorescence anisotropy or fluorescence polarization is the phenomenon where the light emitted by a fluorophore has unequal intensities along different axes of polarization.Early pioneers in the field include Aleksander Jablonski, Gregorio Weber, and Andreas Albrecht. This is the most common form of fluorescence microscopy today. Fluorescence Microscopy is a precise and widely employed technique in many research and clinical areas nowadays.
