摘要: 为了满足现代手机镜头对高像素、小型化以及无杂散光的要求,采用光学塑料非球面技术以及蒙特卡洛光线追迹法,使用CODEV光学设计软件,设计了1款三单元5106像素的手机镜头。同时,运用LightTools光学分析软件进行杂散光分析。结果表明,该镜头的F数为2.6,全视场角为72.9,系统总长为3.1mm。最终组装产品的性能测试结果能满足设计要求,且无不可接受的杂散光。Abstract: In order to meet the demand for high pixels, miniaturization and without stray light of a modern mobile phone lens, a three-unit 5106 pixel optical system based on CODEV software was designed by optical plastic aspherical technology and Monte Carlo ray tracing method. Stray light was analyzed based on LightTools software. After theoretical analysis and experimental verification, the results show that the F number of lens is 2.6, the full field of view angle is 72.9, the total length of system is 3.1mm. Performance test results of the final assembled products meet design requirements and have no unacceptable stray light.
