摘要
本文通过测量待检透镜焦面上的分划板的两刻线对透镜主点的张角测焦距。待检透镜成像质量优良 ,用此种方法测量焦距 ,其相对偏差可达万分之几。通过分析误差源 。
This paper introduces the measuring of focal distance through measuringfield angle of waiting for checking.The imagery quality of waiting for checkinglens is good,its relative error is very small by measuring focal distance usingthis method.We discuss some questions of the measurement by analyzing the errorrusources.
