Study on Detector Arrangement of Single Cell Counter Based on Forward Light Scattering

Light scattering technique is used to measuring the blood cell size in many types of Hematology Analyzers, but How to choose the detection angle of scattered light affect the efficiency of the instrument count. In this paper, axial lighting model is established. Mathematical description of luminous flux and particle size of cell is given. And through numerical calculation, the main factors counting efficiency are analysis.
