    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

    Epifluorescence involves illuminating the specimen from above while in transfluorescence the excitation light comes from below the sample [Weeks, 2004].
