The 1300 megapixel mobile phone camera lens which is composed of five plastic aspheric lenses and an infrared (IR) filter is designed. We use a 1/3 inch (1 inch=2.54 cm) CMOS as the image sensor, and the pixel size is 1.12 mm. The mobile phone lens has an effect focal length of 3.9 mm, an F-number of 2.2, and a field-ofview (FOV) of 78°. All modulation transfer function values at the half limiting frequency are greater than 0.4. Simulation results show that the lens has an excellent imaging performance. The maximal distortion of the lens is less than 2% , the relative illumination is more than 36% , and the tolerance is rather loose. It can satisfy the requirements of practical production.
