为满足市场对超薄广角手机镜头的需求，用光学设计软件Zemax 设计了一款800 万像素超薄广角手机镜头。该手机镜头由4 片非球面塑料透镜和1 片红外滤波片组成。它的总长为3.6 mm、最大视场角为82°、F 数为2.1、畸变小于2 % 。图像采集元件采用的是美国Omni Vision 公司生产的一款型号为OV8858 的互补金属氧化物半导体(CMOS)，每个像素大小为1.12 mm，奈奎斯特频率为446 lp/mm，最大像素为800 万，最大像高为4.57 mm。设计结果显示，在1/2 奈奎斯特频率处的调制传递函数(MTF)均大于0.25，TV 畸变小于1%，成像质量好。公差分析结果较松，易于生产加工。并用光学系统分析软件ASAP 分析杂散光，其结果可被接受。

In order to meet the demand of mobile phone market for the thin and wide-angle mobile phone camera, a thin and wide-angle for 8 mega-pixel mobile phone lens is designed by Zemax. The mobile phone lens is composed of 4 plastic aspheric lenses and a infrared filter, which has a total length of 3.6 mm, a field of view of 82°, a F-number of 2.1, the distortion is less than 2%. It can be used in OV8858 which is a 8 mega-pixel sensor with 1.12 mm pixel size made by Omni Vision, Nyquist frequency is 446 lp/mm, the maximum pixel is 8 million and the maximum image height is 4.57 mm. The design result shows that modulation transfer function (MTF) value at frequency of 224 lp/mm is larger than 0.25, and the maximum TV distortion is lower than 1%. After tolerance analyze, the lens has the high quality of image and good performance. The simulation by ASAP shows that the flare of the lens is slight and acceptable.
