Fluorescence microscope




A fluorescence microscope is an optical microscope that uses fluorescence and phosphorescence instead of, or in addition to, reflection and absorption to study properties of organic or inorganic substances. The specimen is illuminated with light of a specific wavelength, causing the fluorescent molecules in the sample to emit light at a longer wavelength.The excitation wavelength is selected to match the absorption peak of the fluorophores. These fluorescent labels are attached to molecules of interest in the sample, allowing their visualization under the microscope.The lenses are designed to collect light over a wide range of angles.use sensitive detectors, such as photomultiplier tubes (PMTs) or charge-coupled devices (CCDs),and convert the incoming light into electronic signals for image formation. is a powerful tool in cell biology, molecular biology, neuroscience, It allows researchers to visualize and study specific molecules or structures within cells and tissues, providing valuable insights into cellular function and dynamics.
