摘要
为满足高解析力、广角手机镜头发展需求,基于ZEMAX设计了一款1300万像素的广角手机镜头.镜头由6片塑料透镜和近红外滤光片构成,系统焦距为3.36mm,全视场84°,系统F数为2.6,系统总长5.4mm,像高5.86mm.采用O mniVision公司的OV13B10图像传感器,分辨率为4208pixel × 3120pixel,像元尺寸1.12μm × 1.12μm.设计结果表明,在奈斯奎斯特频率为223lp/mm处,中心视场调制传递函数(MTF)优于49%,0.7以内视场MTF优于33%.全视场最大RMS半径3.192μm,最大畸变-3.948%.全视场相对照度均优于38%.研究结果为高像质、广角手机镜头提供设计参考.
Abstract
In order to meet the development requirements of high resolution and wide-angle mobile phone lens,a 13 megapixel wide-angle mobile phone lens was designed based on ZEMAX.The lens is composed of six plastic lenses and a near-infrared filter with the focal length of the system of 3.36mm,the field of view of 84°,the F-number of the system of 2.6,and the total length of the system and the image height of 5.4mm and 5.86mm.Image sensor OV13B10 from Om-niVision is adopted,with a resolution of 4208 pixelX3120 pixel,pixel size of 1.12pmX 1.12pm.The design results show that the modulation transfer function(MTF)of the central field of view is greater than 49%and the MTF of the field of view within 0.7 is greater than 33%at the Nyquist frequency of 2231p/mm.The maximum RMS radius in full field of view is 3.192pm and the maximum distortion is-3.948%.The full field of view relative illuminance is better than 38%.The research provides a design reference for the high image quality,wide-angle mobile phone lens.
