| Abstract: | In measuring the focal distance of lens, the experimental accuracy is often affected by the poor quality in the formation of images. This paper analyses the cause of the poor quality in the formation of images and explains, both in theory and experimental practice, the effect and function on the quality in the formation of imagines and the measurement of the focal distance of lens after diaphragm is added. |
