Means of detecting magnified light given off by a specimen, particularly in response to the shining of light on the specimen where the illuminating light is then removed using filters.
Specifically, it is not the light that is illuminating the specimen that is being observed but instead photons that have been absorbed and then reemitted at a longer wavelength, particularly UV light that is reemitted as visible light. See fluorescence.
