摘 要: | 本文介绍了一种新的测量凹透镜焦距的方法,复合成像法。该方法通过对凹透镜的两次成像过程中透镜位移的测量,再利用贝塞尔公式将凹透镜的焦距间接测量出来。此方法具有测量精度高,相对误差约为1%,且操作较为简单等优点。

Abstract: | This paper introduces a new method in deterimining the focal length of concave lens:the method of compound formation of image.It measures the lens displacement in the course of image for concave lens and measured indirectly the focal length of concave lens to use the bessal formula again.This method has many advantages having higher precision with average error nearly one per cent and has simpler operation,etc. |

Keywords: | the focal length of concave lens determining method the method of two times formation of image the method of compound formation of image |
