摘要

摘要: 通过利用ZEMAX光学工程设计软件设计了一款适用于手机的2倍内置式光学变焦距镜头。镜头仅由4片非球面的塑料透镜和1片BK7的红外滤光片构成，能够达到285lp/mm的空间频率，可匹配1.75m的COMS图像传感器，全视场RMS半径均小于艾利斑半径，全视场最大畸变小于3%，MTF值在1/2奈奎斯特频率处的大部分视场大于0.5，总长度小于9.2mm。整个变焦距系统结构紧凑，分辨率高，成本低，可满足手机镜头光学变焦的要求。

Abstract: A compact 2X optical zoom lens system for mobile phones was designed with ZEMAX. The system consists of 4 plastic aspheric lenses and an IR filter. The limiting resolution is 285lp/mm, which matches the CMOS image sensor of 1.75m pixel size. In the whole field of view (FOV), the RMS raidus is less than airy disk and the maximum distortion is less than 3%, the MTF at the half Nyquist frequency (285pl/mm)of CMOS in most part of the FOV were greater than 0.5,and the length of the optical zoom lens system is less than 9.2mm. It is compact in structure, high in resolution and low in cost, which meets the zoom lens system requirements of mobile phones.
