<p>A flow cytometer includes a flow cell (6) for flowing a sample liquid (T) in a flowing direction, to form a sample flow the sample liquid containing particles to be analyzed, a laser diode (1) radiating a laser beam (LB) having an elliptic cross section, a beam collimating section (3) for collimating the laser beam radiated from the laser diode (1), a beam spot forming section for focusing the collimated beam at the sample flow in the flow cell (6) to form a beam spot (BSO), and a light receiving section for receiving light generated from the particles at the beam spot (BSO) to detect optical information of the particles, wherein the laser diode (1) is arranged such that a minor diameter of the elliptic section of the laser beam is parallel to the sample flow. <IMAGE></p> |
