研究凸透镜成像规律实验是初中物理中的一个重要实验，不管是旧版教材，还是新版试验教材，均将它列为学生分组实验，足见其重要性。然而在很多学校，由于实验条件限制或学生具体情况不同，仍需教师在课堂上演示该实验。目前各学校配置的研究凸透镜成像规律的实验装置仍为光具 The study of the convex lens imaging law experiment is an important experiment in the junior middle school physics. Whether it is the old version of the textbook or the new version of the experimental textbook, it is classified as a student group experiment, which shows its importance. However, in many schools, teachers are required to demonstrate the experiment in class due to experimental conditions or different student circumstances. At present, the experimental device for studying the lenticular imaging law configured by each school is still an optical device.
