摘　　要：文章利用光学设计软件ZEMAX以及缩放法设计一款焦距50mm,像素为500×104的非球面摄影镜头。该镜头的像元大小为2.2μm,镜头采用的初始结构为双高斯摄影物镜结构。该设计的最大优点在于畸变极小,小于0.05%,各个视场的调制传递函数(MTF)值超过一般要求值,在奈奎斯特频率1/2处视场的MTF值等于0.585,0.7视场之内的MTF值等于0.464,各个视场的照度都能达到95%以上。An aspheric photographic lens which has 50 mm focal length and 500 × 104 pixels is designed by using the optical design software ZEMAX and scaling method. Double Gauss lens is used as the ini- tial structure, and the pixel size of this lens is 2.2 μm. The advantage of this design is that the lens distortion is less than 0.05 %. The modulation transfer function（MTF） value of every field coverage is better than normal value and equal to 0. 585 when in the half-Nyquist frequency field coverage, and it is equal to 0.464 when in 0.7 field coverage. The irradiance of every field coverage can reach more than 95 %.
