摘要	The paper introduces a kind of super relative aperture condenser which has the strcuture of spherical Fresnel surface with catadioptric projection optical system, it would improve the condensing capacity and light efficiency substantially. The condenser is composed of two sections with a center and an outer ring, the center region adopted the basic structure of the Fresnel lens with the Fresnel of laplace domain continuous curve transmission type, and the outer structure which achieve light collimating or focusing by total reflection is stepped. The paperstudies the parameter and alforithm of this catadioptric dual-zone Fresnel condenser and gives the surface data of total reflection region. Based on the method of establishing the entity model, we design a set of lens with the relative aperture F=0.3, simulate the condensing ability of the lens by the simulation software, and verify that the lens have a very good effect on focusing.
