Description

technical field [0001] The invention relates to the technical field of biotechnology time-resolved fluorescence acquisition systems, in particular to a fluorescence excitation acquisition system that generates fluorescence in a specific band by exciting an analyte solution to collect fluorescence signals. Background technique [0002] Some analyte solutions can emit light with a longer wavelength than the excitation light when irradiated by light. This substance can absorb and store energy (such as light energy, chemical energy, etc.) from the outside world, and enter the excited state; when it returns from the excited state When the ground state is reached, the excess energy is emitted in the form of electromagnetic radiation (ie, luminescence), which is called fluorescence. Two conditions must be met to produce fluorescence: the molecules in the analyte solution must have the same frequency as the irradiated light; the molecules that absorb the same energy as their own cha...
