1300万像素手机镜头设计
Design of 13 mega-pixel mobile phone lens based on code V
摘要
为满足高像素手机的要求,本文根据光学成像理论,利用code V软件设计出一种1300万像素手机镜头。为了增加自由度,减小像差,得到更好的像质,本文采用非球面表面进行光学设计。该镜头由五片非球面镜片、一片滤光镜组成。设计得到光圈值2.2,半视场角35°,有效焦距3.6 mm,镜头总长3.6 mm的轻薄型手机镜头。最终中心视场在中间频率处(即223 lp/mm)的MTF值大于0.6,在高频处大于0.2,在0.8视场中频MTF值大于0.4,可见优化完毕后成像效果可满足使用要求。
Abstract
In order to meet the unmet commerce needs of high pixel mobile phone, more and more designs come into being. According to the theory of ray optics, a 13 mega-pixel mobile phone lens was designed based on code V, an optical design software. It consists of five aspherical lenses and a filter. The F-number of the lens is 2.2, the half field of view is 35 degrees, the effective focal length is 3.6, and the total length of the lens is 3.6 mm. The MTF(modulation transfer function) of central field of view is greater than 0.6, the high frequency is greater than 0.2 and in the 0.8 field of view the middle frequency is greater than 0.4. In a word, the lens can meet the requirement of the high imaging quality camera.
