| Abstract: | 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. |
