Fluorescence immunoassay quantitative analyzer

The invention discloses a fluorescence immunoassay quantitative analyzer. The fluorescence immunoassay quantitative analyzer comprises a main machine frame, a power supply, an optical module and an optical bracket, wherein the power supply, the optical bracket and a driving motor are fixed to the main machine frame; the optical module is arranged on the optical bracket; an ultraviolet light source is arranged in the optical module; a shielding cover is arranged on each of the power supply and the optical module. According to the fluorescence immunoassay quantitative analyzer, the ultraviolet light is taken as an excitation light source; the wavelength difference between the fluorescence excited when the ultraviolet light is taken as the excitation light source and the ultraviolet light is large, and after the light passes through a filter, the reflected ultraviolet light and other external interferential light are filtered by the filter, so that the ultraviolet light cannot interfere with the intensity of the fluorescence, and the influence on the detection accuracy caused by the excitation light source is avoided.
