满足上述配置的摄远镜头能够修正各种像差,提高摄远镜头的分辨率。
较佳地,该摄远镜头满足下列关系式:
1.0<R2/R3<2.0;
其中,R2为该第一透镜E1的像侧面S2的曲率半径,R3为该第二透镜E2的物侧面S3的曲率半径。
满足上述配置的摄远镜头能够确保摄远镜头易于组装,进而提升了摄远镜头的生产效率。
较佳地,该摄远镜头满足下列关系式:
0<R7/R8<2.0;
其中,R7为该第四透镜E4的物侧面S7的曲率半径,R8为该第四透镜E4的像侧面S8的曲率半径。
满足上述配置的摄远镜头能够压低摄远镜头的光线入射角度,视场角较小,并且摄远镜头具有较高的芯片匹配度。
较佳地,该摄远镜头满足下列关系式:
|(R11-R12)/(R11+R12)|≦0.5;
|(R9-R12)/(R9+R12)|≦1.0;
其中,R9为该第五透镜E5的物侧面S9的曲率半径,R11为该第六透镜E6的物侧面S11的曲率半径,R12为该第六透镜E6的像侧面S12的曲率半径。
满足上述配置的摄远镜头能够修正边缘像差,可使镜片厚度相对匀称及使中心到边缘整体像质比较均匀。
成像时,光线穿过6片透镜后经过具有物侧表面S13及像侧表面S14的滤光片E7后成像于成像面S15。
在某些实施方式中,第一透镜E1、第二透镜E2、第三透镜E3、第四透镜E4、第五透镜E5及第六透镜E6都为非球面透镜。
非球面的面形由以下公式决定:
Figure PCTCN2016083097-appb-000001
其中,h是非球面上任一点到光轴的高度,c是顶点曲率,k是锥形常数,Ai是非球面第i-th阶的修正系数。
