设计了一款折叠式微型数码镜头。该镜头的F数为3,视场角为52°,总长度为6.67 mm。该系统具有良好的成像品质。子午和弧矢MTF曲线在0.73视场、空间频率为285 lp/mm值大于0.3,系统的畸变约为-1.3%,该系统在最大视场处的相对照度约为70%左右,横向色差在0.9视场附近最大,约为0.42μm,小于单个像素的尺寸。

The folded miniature digital lens with F-number of 3,field of view of 52°and total length of 6.67 mm is designed.The design result shows that the lens system has the excellent image quality.The meridional and sagittal modulation transfer function（MTF） curves at 0.73 field of view,spatial frequency of 285 lp/mm are more than 0.3.The distortion is about-1.3% and the relative illumination at max field of view is about 70%.The later al color is about 0.42 μm,which is less than the pixel size.
