WebFluorescence microscopy uses the concept of fluorescence over normal light. When a fluorescent substance is excited with lower wavelength, the energy emitted is in the form of light with higher wavelength from visible spectrum. WebOtherwise, the much brighter excitation light overwhelms the weaker emitted fluorescence light and significantly diminishes specimen contrast. Stokes’ Law When electrons go from the excited state to the ground … WebIn epifluorescence microscopy, both the excitation and emission light travel through the same objective. This arrangement—where both the illuminated and emitted light travels through the same objective lens—is referred to as epifluorescence microscopy, where “epi” is borrowed from the Greek to mean “same”. blackrock sector managed growth
