Design of 13 megapixel wide-angle mobile phone lens
In order to meet the development requirements of high resolution and wide-angle mobile phone lens,a 13 megapixel wide-angle mobile phone lens was designed based on ZEMAX.The lens is composed of six plastic lenses and a near-infrared filter with the focal length of the system of 3.36mm,the field of view of 84°,the F-number of the system of 2.6,and the total length of the system and the image height of 5.4mm and 5.86mm.Image sensor OV13B10 from Om-niVision is adopted,with a resolution of 4208 pixelX3120 pixel,pixel size of 1.12pmX 1.12pm.The design results show that the modulation transfer function(MTF)of the central field of view is greater than 49％and the MTF of the field of view within 0.7 is greater than 33％at the Nyquist frequency of 2231p/mm.The maximum RMS radius in full field of view is 3.192pm and the maximum distortion is-3.948％.The full field of view relative illuminance is better than 38％.The research provides a design reference for the high image quality,wide-angle mobile phone lens.
