WebThe illustration below shows the typical light path of an epifluorescence microscope. Most microscopes that are used for cell biology are arranged so that the light travels through the objective lens to illuminate the sample, and then the light emitted from the sample travels back through the same objective to the detector. The specimen is illuminated with light of a specific wavelength (or wavelengths) which is absorbed by the fluorophores, causing them to emit light of longer wavelengths (i.e., of a different color than the absorbed light). The illumination light is separated from the much weaker emitted fluorescence through the use of a spectral emission filter. Typical components of a fluorescence microscop…
