Fabrication process and measurement of injection molding aspheric lens

The aspheric optical plastic injection molding technology has many advantages such as lightweight, low cost, saving assembly work, easy mass production and so on. It is the main processing method for aspheric optical plastic lenses. This paper systematically summarizes the error sources in the process of optical plastic injection molding, and displays the current development status of error detection technologies. A method based on wavefront sensing technology for transmission aspheric optical lens error detection is proposed. Finally, this paper gives the prospects for the development of error detection technologies applied in aspheric optical lens.
