摘要
为适应某些特殊场合需要,隐秘型CCD摄像光学系统的广角视场、长工作距离、小空间尺寸、隐蔽性能好、成像质量优良等特殊要求,采用孔径光阑置于镜头前方的新型反远摄结构,并运用了3个非球面。对其设计思想、像差特点进行了分析,设计出焦距1.6mm、视场80°、相对孔径1:3.5的隐秘型CCD摄像镜头,并给出了像差和传函计算曲线。
In order to meet the needs of some special occasions, including some special demands wide angle field-of - wiew, long working distance, small space size, well hidden performance as well as good imaging quality ofhidden-type CCD optical system, we use a new type of anti-telephoto structure which its apeture stop is located in the front of lens, also use three non-spherical surface. The design considerations and the characteristics of aberrations is discussed. A useful design result with f＇= 1.6ram, 2ω = 80°, D/f＇= 1：3.5 is provided. The aberration curves and calculated MTF of the micro retrotelephoto lens are also given.
