Analysis and Calibration of Spherical Aberration and Chromatic Aberration in Lens Imaging

Because the spherical aberration and chromatic aberration of the thin lens has serious effect on the effect of imaging,there exist a great measurement error and it is difficult to determine the correct position of the focus when students measure the focal length of the lens.In this paper,the causes for the spherical aberration and chromatic aberration in thin lens imaging were analyzed.The influence of the spherical aberration and chromatic aberration was effectively reduced by placing the diaphragm and filter between the light source and the lens,thereby,reducing the relative error of the experiment.
