摘要
为了提高变焦系统的性能,使其拥有良好的像质,简化系统结构,方便机械加工、装调,在小变倍比变焦距光学系统设计过程中引入了非球面设计。利用光学设计软件ZEMAX对系统在长、中、短3个焦距位置进行优化设计,由此得到了一焦距15.6196～23.4084mm,视场±10.29°～±7°的变焦系统,系统由4组6片透镜组成,其中包括1个非球面。该系统具有结构简单紧凑、成像质量较好等特点。
In order to improve the performance of the zoom system,enhance image quality,simplify the structure,conduce the machining、alignment,aspheric surface is introduced to small ratio zoom system design.The system is optimized in the 3 focal position of long、medium、short with optical design software ZEMAX.A system with focal length of 15.6196 ～23.4084mm,FOV of±10.29°～±7°is completed,which consists of 4 components in 6 pieces including a aspheric surface.The system has the features of simple and compact structure and the good image quality,etc.
