This article describes a simple experiment to accurately measure the focal length and radius of curvature of a medium-size lenticular lens. This method is an improvement on the traditional method, which minimizes the measurement error introduced by the optical bench and the visual error in the traditional method with the accuracy of ± 0.5%. In this paper, examples of measurement results and experimental parameters of thin convex lenses are given.
