    摘要： A cytometer includes an illuminating unit having a laser and a light beam shaping module for shaping and converging the laser beam emitted from the laser. A sample generation unit includes a gas-liquid transmission controlling module and a flow chamber which are connected to each other, so the sample liquid containing the cells to be detected may flow through the flow chamber while being encircled by the sheath fluid. A signal processing unit receives, converts and processes the scattering light emitted from the flow chamber. The signal processing unit includes at least a photoelectric detection module, wherein the light beam shaping module has at least one aspheric collimating lens and a pair of mutually crossing cylindrical lenses, and the numerical aperture of the aspheric collimating lens is at least 0.3.
