针对透镜焦距测量实验中由焦深引起的测量误差,改进了透镜焦距测量实验中的物屏。用此屏测量薄凸透镜的焦距可改善成像焦深现象,同时减小实验所得焦距的离散性。

For the measurement error caused by the depth of focus in the Lens focal length measurement experiment,the screen object in the experiment has been improved by taking a 1mm thick blank screen objects,drilling a hole with diameter 1cm at the center of the screen,inserting two pins through the center of the hole horizontally,leaving their heads toward each other with a 0.5mm gap.Using this screen to measure a thin lens focal length can reduce the error caused by the depth of focus.
