Abstract:

The compact, slim and high pixel mobile phone camera is highly demanded with the development of mobile phone, especially the thinner and thinner request of people. To satisfy this need, a mobile phone lens system composed of 1 glass spherical lens and 3 plastic aspheric lenses was designed with Code V. The F-number was 2.85 and FOV was 61, the effective focal length and back focal length are 5 and 0.468 mm, respectively. A 1/3.2 inch 8 mega-pixel CMOS made by APTINA was taken as the image sensor of the lens assembly, whose pixel size is 1.4 μm and the limiting resolution was 357 lp/mm. The design results shown that the M TF value was more than 0.2 within most fields of view at the Nyquist frequency and more than 0.5 at the 1/2 Nyquist frequency, the maximum distortion was 0.66%. It shows that the lens has good performance and meets practical requirements.
