摘要
Abstract
A continuous zoom optical system with an aperture of 1m and the focus range of 2000-6000mm is designed, which is based on the technical requirements of a kind of large-aperture optical equipment. An appropriate cam mechanism is selected and is designed specifically by comparing the advantages of the former structure of continuous zoom optical system. The static and dynamical analysis of the cam's structure is presented by using FEM software, which is the key element of the structural system. The precision of this continuous zoom optical system is 3.3μm, which meets the measure requirements.关键词
