This article describes the working principle of a continuous zoom optical lens as well as the ray tracing calculation.The error of cam profile designed with 2D method is analyzed.By the detailed design with Pro/E 3D software,the motion behavior of zoom group and compensation group in continuous zoom optical system is reflected,and design accuracy of cam profile is improved.
