| 摘 要： | 激光粒度仪中使用的矩形样品池的透明壁会对颗粒的散射光产生全内反射效应，该效应将限制光电探测器可接收到的散射光的散射角上限。针对此问题设计了一种棱镜式样品窗，可以有效地扩大可接收散射光的散射角范围。根据不同的需要给出了几种可以选择的方案。

| Abstract: | The rectangle sample cells are widely used in laser particle sizers up to now.The wall of the rectangle sample cell will produce the entirely inner reflection to the light scattered by particles.This entirely inner reflection will limit the upper limit of the receivable angle of the scattered light received by the photoelectric detector.A prism cell was designed for solving the problem,which can expanding the upper limit of the receivable angle of scattered light.Some optional schemes were put forward for different demands. |
