Herein, to achieve high-performance mobile phone lens optical system with a large view field, low cost, and high resolution, two single-center and ultra-wide-angle optical systems of mobile phone lens with different filtering methods are designed based on ZEMAX software, which are matched with a curved sensor. The two optical systems comprise four concentric plastic lenses, a curved surface filter, or an IR-CUT film with the system F-number of 1.8, view field of 130°, and focal and total lengths of the system of 2.64 mm and 4.1 mm, respectively. The modulation transfer function (MTF) value of the central view field is greater than 0.5 and 0.3 at 200- and 400-lp/mm Nyquist frequencies, respectively. The MTF value of less than 0.7 view field is greater than 0.2 at 400-lp/mm Nyquist frequency. The relative illumination of full view field is greater than 0.42. The maximum RMS radius is less than 3.75 μm, which satisfies the requirements of mobile phone lens imaging. The design of an ultra-wide-angle, short focus, and compact optical system is accomplished with high machinability and high imaging quality.
