High Resolution Optical Design of Mobile Phone Camera
Abstract：By the aid of optical design soft are ZEMAX, an eight mega-pixel mobile phone camera lens matched with one CMOS image sensor of 1.40μm pixel size was designed. The system includes three plastic aspheric lenses, a glass aspheric and an IR cut filter. The effective focal length is 3.25mm, the F-number is 2.8 and FOV is 60°.The design result shows that RMS spot radius at different field are less than 1.4μm.Distortion is less than 2%, total length is 5.38mm and half image height is 2.069mm.Comply with the design requirements, and has a certain reference value to design of mobile phone camera lens
