By controlling the light emitting time of the sub-light sources 112 with different spectrums, each sub-light source 112 emits light with different wavelengths to the reaction cup 4 for detection respectively, so that the sub-light sources 112 with different spectrums correspondingly detect different projects, the result is simple, and the same coagulation optical path system 10 can meet the requirements of a plurality of detection projects.
