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.
