(57) [Summary] [Purpose] A prism or a diffraction grating is used in a device that analyzes the particles by irradiating a sample liquid stream containing particle components such as blood and urine with light to detect signals from the particles. Obtain the spectrum of the optical signal and get more detailed particle information. [Structure] Fluorescence from particles is dispersed by a prism 28 or a diffraction grating for each wavelength, and the intensity of the obtained fluorescence spectrum is amplified by an image intensifier 30, and the intensity for each wavelength is measured by an image sensor 34. To measure. |
