TITLE APPARATUS FOR DETECTING AND MEASURING FLUORESCENCE EMISSION INVENTORS Ulrich Schreiber William Vidaver ABSTRACT OF DISCLOSURE Apparatus for detecting and measuring fluorescence emission comprising a fluorometer probe including a light emitting means for illuminating the object under study, a red cut-off filter, a light sensitive detector for obtaining the fluorescence signal from the object, and a preamplifier connected to the phototransistor for amplifying the said signal to a first level, and power and control unit including electronic indicating means. In the preferred embodiment the sensor and emitter are a light emitting diode (LED) and a phototransistor arranged in piggy-back relation with the LED having an epoxy body acting as a fluorescence light guide from the object to the phototransistor.
