Noun

[edit]

transfluorescence (uncountable)

  1. (physics, microscopy) Fluorescence of a material when the source of stimulating radiation is behind the object, from the point of view of the observer.
    • 1990, Linda J. Goff, Annette W. Coleman, chapter 3, in Kathleen M. Cole, Robert G. Sheath, editors, Biology of the Red Algae, page 45:
      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.
    • 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:
      Likewise in fluorescence applications, an epifluorescence configuration is normally chosen over transfluorescence.
    • 2006, Steven Saliterman, Fundamentals of BioMEMS and Medical Microdevices[1], page 319:
      Epifluorescence involves illuminating the specimen from above while in transfluorescence the excitation light comes from below the sample [Weeks, 2004].
