This optical lens CAD software system has carried out the integrative unitization of optical and mechanical design based on the communicative technology of multi-database. So the traditional design of an optical lens with two stages of optical and mechanical method has been changed into one time design for the first time. The system can supply such program blocks as those for creating optical system

tracing rays

computing optical aberration

designing zoom lenses

evaluating image quality

and interconnecting systems

etc.All of them will accomplish optical system design

parameter computation

creation of the database for optical design and system parameters.After the database file parameters and optical system model are selected

the system control program runs the database program for the self-creating public function and the mathematical models of mechnnical components.Then the optical lens CAD software system automatically generates the mechanical graphics of components. In this way

the autodesign of an optical lens has been realized.Finally

the article illustrates the example of designing a zoom lens for professional TV camera.
