Automatic design method for miniature aspheric lens based on modified basin-hopping algorithm.

Abstract

Against the backdrop of the rapid development of the miniature camera lens manufacturing industry, with an annual output exceeding 4 billion units (including various lenses for mobile phones, automobiles, security, etc.), the design of highly aspherical miniature camera lenses has become increasingly crucial. Traditional optical design methods rely heavily on designer intervention and are optimized step by step through a trial-and-error approach, which consumes a great deal of time and effort. To address this, this paper innovatively proposes a design method based on the modified basin-hopping (MBH) algorithm, enabling the rapid and automatic design of highly aspherical miniature camera lenses without the need for designer intervention throughout the process. Users only need to input design requirements, and the program can automatically generate multiple solutions. Designers simply need to select from the output solutions. In this paper, this method is successfully applied to design two different types of miniature aspheric camera lenses: a 4P (4 Plastic lenses) mobile phone lens with highly aspheric surfaces and an ultra-wide-angle ADAS (advanced driver assistance systems) lens. The designed lenses exhibit excellent imaging quality. This method effectively shortens the development-to-market cycle and reduces the engineering design threshold, fully demonstrating its innovation, effectiveness, and practicality.
