description The invention discloses a waveguide design for an on-chip fluorescence dispersion light path of a flow cytometer, which comprises a prism group and a waveguide array, the prism group is used for carrying out dispersion separation on original fluorescence emitted by cells in the on-chip fluorescence dispersion light path of the flow cytometer so as to output separated fluorescence of each wavelength; the waveguide array is arranged behind the separated fluorescent light of each wavelength, light with different wavelengths in the separated fluorescent light of each wavelength is guided into different waveguides of the waveguide array, and the light with different wavelengths is further separated in space through the bending directions of the different waveguides in the waveguide array. A higher linear dispersion rate is realized in a small-size range, and the adaptation requirements of a PMT or other photoelectric detection devices are met. According to the invention, enough dispersion rate is still realized un
