astigmatism aberration

A new method so called reflecting projection method is used to observe and measure the tangential focal line, sagittal focal line and astigmatism aberration of lens.

介绍一种观察和测量透镜子午焦线和弧矢焦线以及像散差的新方法 ,这种方法可以将透镜的子午焦线和弧矢焦线放大并直接投射到几米到十几米外的演示屏幕上 ,易于观察 ,而且可以准确测量出透镜的像散差 ,同时还可以演示像散光束的传播规律 ,生动直观 ,效果很
