Abstract
A particle analyzing apparatus includes a flow device having a light-transmissive flow cell for allowing subject particles in a sample liquid to flow in a separated state, a laser beam illuminator for illuminating a subject particle flowing in the flow cell with a laser beam and a coherence lowering device for lowering coherence of the laser beam. The particle analyzing apparatus further includes an image capturing device receiving light from the subject particle, for capturing an image of the subject particle and an image processor for processing and analyzing the captured image of the subject particle. By use of the coherence lowering device, both temporal and spatial coherence of the laser beam is lowered. Thus, image quality is improved and a high quality particle image can be obtained which is bright and high in S/N ratio.
