摘要
电润湿液体透镜是一种可以通过改变两端加载电压从而改变自身光焦度,而不需要改变光学间隔的一种透镜。基于液体透镜所设计的变焦光学系统可以大大减少传统机械变焦光学系统的复杂度。基于康宁A39液体透镜,利用ZEMAX仿真,在20 D的光焦度变化范围内设计了一款焦距变化为16~32 mm,视场角变化为32°~16.36°,变倍比为2,短焦F数为6.3,长焦F数为12.8,且最大口径不超过10 mm的小型二元单液体透镜变焦光学系统。实验结果表明,该系统成像质量良好,在工业镜头等领域有广泛的应用前景。
Electrowetting liquid lens is a type of lens that can change its own optical power by changing the applied voltage at both ends,without changing the optical spacing.Therefore,the zoom optical system designed based on liquid lenses can greatly reduce the complexity of traditional mechanical zoom optical systems.This article is based on the Corning A39 liquid lens and uses ZEMAX simulation to design a small binary single liquid lens zoom optical system with a focal length variation of 16~32 mm,field of view angle variation of 32°~16.36°,zoom ratio of 2,short focal F-number of 6.3,long focal F-number of 12.8,and a maximum aperture of 10mm within a 20 D range of optical power variation.
