    • The present invention relates to a flow cytometer, comprising a light source, a light beam shaping module for collimating and converging a light beam emitted from the light source so that the light beam irradiates samples to be detected, a sample generation unit, which comprises a gas-liquid transmission controlling module and a flow chamber that are interconnected, and a signal processing unit, for collecting, photoelectrically converting and analyzing the scattered beam emitted from the flow chamber. The light beam shaping module comprises a first cylindrical lens and a second cylindrical lens for respectively converging the light beams in two directions. In the present invention, the spot converged at the cell-interrogation zone of the flow chamber is flattened to avoid instability of the fluid which in turn leads to instability of the excited optical signal, and consequently the stability and reliability of the system are improved.
    • 流式细胞仪本发明涉及一种流式细胞仪,包括光源,光束整形模块,用于对从光源发射的光束进行准直和会聚,使得光束照射要检测的样品;样品产生单元,其包括 气液传输控制模块和流动室,以及信号处理单元,用于对从流动室发射的散射光进行光电转换和分析。 光束整形模块包括用于分别在两个方向上会聚光束的第一柱面透镜和第二柱面透镜。 在本发明中,在流动室的细胞询问区收敛的光斑被平坦化以避免流体的不稳定性,从而导致激发光信号的不稳定性,从而提高了系统的稳定性和可靠性。
