摘要
基于薄透镜焦平面和副光轴的性质,提供了一种用平行光测量透镜焦距的新方法.该方法中的入射光平行于待测透镜的副光轴而非主光轴.该方法的利用可以加深对薄透镜主光轴、副光轴、焦平面等光学概念的理解和应用,进一步理解近轴成像的含义.
A novel way for measuring the focal length of the thin lens by parallel light is provided based on the character of focal plane and secondary optical axis. This parallel light in the method is not the light parallel to the main optical axis but secondary optical axis. This method can help us to understand and apply the axis,side axis,focal plane of thin lens and optical concepts,and to further understand the paraxial imaging meaning.
