Title
(ZH) 摄像透镜、摄像光学装置及数码设备
Abstract
(ZH)

本发明提供一种摄像透镜、摄像光学装置及数码设备,摄像透镜从物方依次由至少一个物方凸形状的正透镜、负透镜、至少一个具有非球面的透镜构成,正透镜与负透镜邻接配置,满足条件式:0.1<Ton/Dopn<7,0.1<(Rona-Ronb)/(Rona+Ronb)<1.5,0.3<Yˊ/TL<0.9(Ton:位于最靠物方的负透镜的光轴上的厚度,Dopn:位于最靠物方的负透镜与邻接于所述负透镜的物方的正透镜之间的光轴上的间隔,Rona:位于最靠物方的负透镜的物方的面的近轴曲率半径,Ronb:位于最靠物方的负透镜的像方的面的近轴曲率半径,Yˊ:最大像高,TL:从最靠物方透镜面的面顶点到像面的光轴上的距离(在包含平行平板的情况下为空气换算长度))。
