Abstract
A flow cytometer includes a flow cell for flowing a sample liquid in a flowing direction, to form a sample flow the sample liquid containing particles to be analyzed, a laser diode radiating a laser beam having an elliptic cross section, a beam collimating section for collimating the laser beam radiated from the laser diode, a beam spot forming section for focusing the collimated beam at the sample flow in the flow cell to form a beam spot, and a light receiving section for receiving light generated from the particles at the beam spot to detect optical information of the particles, wherein the laser diode is arranged such that a minor diameter of the elliptic section of the laser beam is parallel to the sample flow.
