Meanings
-
(qualifier:microscopy, uncountable) Fluorescence of a material when the source of stimulating radiation is behind the object, from the point of view of the observer.
For example, in contrast to transfluorescence microscopes, the intensity of illumination and consequently the amount of excitation energy increases as a function of increasing magnification.
1990, Linda J. Goff, Annette W. Coleman, chapter 3, in Kathleen M. Cole, Robert G. Sheath, editors, Biology of the Red Algae, page 45:Likewise in fluorescence applications, an epifluorescence configuration is normally chosen over transfluorescence.
1999, Andrew Bullen, Peter Saggau, “Optical Recording from Individual Neurons in Culture”, in Uwe Windhorst, Håkan Johansson, editors, Modern Techniques in Neuroscience Research, page 98:Epifluorescence involves illuminating the specimen from above while in transfluorescence the excitation light comes from below the sample [Weeks, 2004].
