Abstract
As the non-spherical optical lens in the performance much better than the spherical lens, has been widely used in recent years, but the manufacture and testing of non-spherical lens is much more difficult than spherical. In this paper, a non-spherical optical lens manufacturer for the study as, according to classification of non-spherical lens materials research, summed up most reasonable manufacturing. Include the following: 1. Analysis of the various non-spherical optical lens manufacturing and testing methods and their advantages and disadvantages, to clarify the manufacture and testing of non-spherical status and significance. 2. Introduced several kinds of processing methods, and analyzes their advantages and disadvantages, and according to the needs of the present research, the final selection of the molding manufacturing methods, and used car lens, the design of a suitable molding mold.
Key words: Aspheric turning The injection molding moulded Car lens
