摘要
为了满足市场对微型、简单化手机摄像镜头的需求,运用光学设计软件CODE V,结合非球面透镜理论,设计出用于可见光波段且符合结构简洁、生产成本低的要求的手机定焦镜头。该镜头F数为2.05,视场角为62°,半像高为2.4 mm,系统总长度为5.59 mm。为了使结构紧凑并且最大限度地降低生产成本,在结构设计中采用非球面的塑料镜片。设计结果显示:镜头的适应像素尺寸是1.1 μm×1.1 μm,相应的尼奎斯特频率为454 lp/mm,在1/2尼奎斯特频率处绝大部分视场调制传递函数(MTF)值大于0.4,各个视场的横向像差均小于9.26 μm,均方根(RMS)半径都在艾里斑之内,畸变小于1%,获得良好的成像效果。
Abstract
Combining the aspherical lens principle, a fixed-focus lens with compact structure and low cost is designed with the optical system design software CODE V to meet the requirement of the mobile communication on miniaturization and simplification of camera lenses. For the designed lens, the F number is 2.05, the angle of vision is 62°, the half image height is 2.4 mm, and the total length of the system is 5.59 mm. The aspherical lens made of plastic is used to reduce the size and save production cost in the structural design. The design result shows that the pixel size of the lens is 1.1 μm×1.1 μm, the corresponding Nyquist frequency is 454 lp/mm, the modulation transfer function (MTF) values of most FOV at half Nyquist frequency are more than 0.4, transverse aberration of all FOV is less than 9.26 μm, the root-mean-square (RMS) radii are less than Airy disk, and the distortion is less than 1%. The designed lens has an excellent imaging performance.
