【摘要】：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。
[Abstract]:In order to meet the market demand for ultra thin and wide angle mobile phone, an optical design software Zemax is used to design a 8 million pixel ultra thin wide-angle mobile phone lens. The mobile phone is made up of 4 aspherical plastic lenses and 1 pieces of infrared filter. Its total length is 3.6 mm, the maximum field angle is 82 degrees, the number of F is 2.1, and the distortion is less than 2%. The image acquisition element is a complementary metal oxide semiconductor (CMOS) produced by Omni Vision company in the US. The size of each pixel is 1.12 mm, the Nyquist frequency is 446 lp/mm, the maximum pixel is 8 million, and the maximum image height is 4.57 mm. The design results show that the modulation transfer function (MTF) at the 1/2 Nyquist frequency is more than 0.25, the TV distortion is less than 1%, and the imaging quality is good. The result of tolerance analysis is looser, and it is easy to produce and process. The optical system analysis software ASAP is used to analyze the stray light, and the results can be accepted.
