    • A fertility analyzer includes a laser beam impinging on a sperm sample in a capiliary, a first optical system including at least a first lens focusing the laser beam in the sample, and a second optical system including at least a second lens, a first diaphragm determining the volume element of the sample to be monitored, a second diaphragm determining the space angle of scattered light and a light intensity detecter. A signal processing device stores the signals from the light detector during a predetermined time separately for beams outgoing from the sperm sample in at least two chosen directions and computes at least two features having relation to the fertility of the sperm sample. A separator included in the combination of the first and second optical systems sorts out a determinable small section of the beam outgoing from the sperm sample in a direction lying in a plane approximately parallel to a plane including the capillary.
    • 生殖分析仪包括照射在毛细针上的精子样品的激光束,至少包括将激光束聚焦在样品中的第一透镜的第一光学系统和包括至少第二透镜的第二光学系统,第一光阑确定 要监视的样本的体积元素,确定散射光的空间角的第二光阑和光强度检测器。 信号处理装置在预定时间内分别存储来自光检测器的信号,用于在至少两个选择的方向上从精子样本出射的束,并且计算与精子样品的生育力有关的至少两个特征。 包括在第一和第二光学系统的组合中的分离器在位于大致平行于包括毛细管的平面的平面中的方向上分离出来自精子样品的束的可确定的小部分。
