Aspheric optical elements have been applied in many kinds of advanced optical systems especially in military and space optic fields accompanied by the development of the optic science.
Ultra-precision aspheric surface can improve the optical performance effectively. It also can reduce the dimensions and the weights of the systems, which is the major advantage of it. In order to achieve the high-precision aspheric surfaces, some methods of the aspheric fabrication and metrology have been generated such as the diamond turning, molding, holography and some other special polishing manners based on the traditional craft production and measurement.
In this article we described the manufacturing methods of aspheric element in brief and then we posed one way of the production about the aspheric surface. We introduce not only the manufacturing machine and measuring instrument about this kind of element but also the optical and mechanical parameters about the grinding and polishing, as well as technology of the process control.
All devices compose a cycle of the production that is flexible and convenient to generate aspheric elements. It attribute to the high-speed production and improvement of efficiency in the factory.
