The utility model relates to a fluorescence detection device based on the photometer, comprising a light source, a monochromator, a colorimetric cell, a colorimetric utensil frame, a colorimetric utensil, a photoelectric receiving circuit, an amplification display circuit, a fiber, a light baffle plate, a transmission optical absorption chamber and a filter. The utility model uses the characteristics of fiber conducting light wave, which changes the light conduction direction into 90 degrees in the sample cell, so the measured sample is subjected to the light irradiation and gives off fluorescence, the fluorescence is received and amplified by the photoelectric receiving circuit and the fluorescence luminosity value is displayed, only by changing the structure of the colorimetric utensil frame, the use value and the performance-price ratio of the original photometer is enhanced, the utility model not only can detect the absorbance, but also can detect the fluorescence, so the equipment can play a greater role in the fields of medical and health, environmental protection, biological medicine and chemical industry, and education. The utility model can more intuitively explain and instruct the detection principles of the absorbance and the fluorescence and the structures of the two machines in particular to the higher education.
