Design of Thin and Wide-Angle Lens for 8 Mega-Pixel Mobile Phone Camera
In order to meet the demand of mobile phone market for the thin and wide-angle mobile phone camera, a thin and wide-angle for 8 mega-pixel mobile phone lens is designed by Zemax. The mobile phone lens is composed of 4 plastic aspheric lenses and a infrared filter, which has a total length of 3.6 mm, a field of view of 82°, a F-number of 2.1, the distortion is less than 2%. It can be used in OV8858 which is a 8 mega-pixel sensor with 1.12 mm pixel size made by Omni Vision, Nyquist frequency is 446 lp/mm, the maximum pixel is 8 million and the maximum image height is 4.57 mm. The design result shows that modulation transfer function (MTF) value at frequency of 224 lp/mm is larger than 0.25, and the maximum TV distortion is lower than 1%. After tolerance analyze, the lens has the high quality of image and good performance. The simulation by ASAP shows that the flare of the lens is slight and acceptable.
