      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.

      Likewise in fluorescence applications, an epifluorescence configuration is normally chosen over transfluorescence.
    • 2006, Steven Saliterman, Fundamentals of BioMEMS and Medical Microdevices, page 319,
      Epifluorescence involves illuminating the specimen from above while in transfluorescence the excitation light comes from below the sample [Weeks, 2004].
