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… WebNov 13, 2015 · The design of fluorescence illuminators is based on control of excitation light and emission light by readily changeable filter insertions in the light path on the …
