摘　　要：为满足市场对高像素手机镜头的需求,利用ZEMAX光学设计软件,设计了一款800万像素的折衍混合式手机镜头。镜头采用了正-负-正的三片式结构,光阑位于第一片透镜和第二片透镜之间,第二片透镜的前表面为二元衍射面。手机镜头的F数为2.85,全视场64,总长5.9mm,在Nyquist频率处所有视场MTF值均大于0.23,相对畸变小于1%,成像质量良好。公差计算结果表明镜头公差符合加工工艺要求。An 8 mega-pixel hybrid diffractive-refractive mobile phone camera lens is designed with ZEMAX. The system includes three plastic aspheric lenses and an IR filter. The F number is 2.85 and FOV is 64°. The optical total length and back focal length are 5.9mm and 0.6mm respectively. The MTF of the lens at the Nyquist frequency is greater than 0.23 within its full field of view. The relative distortion is less than 1%. The tolerance calculation results show that the tolerance of the mobile phone optical systems meet the processing requirements.
