The apparatus contains a dispersion means (DP) decomposing the incident laser beam into a number of colors (C1-C5) spacially separated from each other. The focusing points of said colors are subsequently traversed by particles contained in the flow. The light from the measuring volume (MV) is conducted via the dispersion means to a light receiving means (AV) in which the light is decomposed again into the individual colors. Due to a switching means (SE), the colors used for the measurment are selectible. Thus, the space of the focusing points used for the measurement may be varied.
