影像撷取镜片组、取像装置及电子装置

Photographing optical lens assembly, image capturing unit and electronic device

Abstract

The invention discloses a photographing optical lens assembly, an image capturing unit and an electronic device. The photographing optical lens assembly includes lens elements including, in order from an object to an image side, a first lens group, a second lens group and a third lens group. The first lens group includes a first lens element and a second lens element. The second lens group includes a third lens element, a fourth lens element and a fifth lens element. The third lens group includes a sixth lens element, a seventh lens element and an eighth lens element. The first lens element has positive refractive power. The seventh lens element has an object-side surface and an image-side surface being both aspheric. The eighth lens element has an image-side surface being concave in a paraxial region thereof, wherein both an object-side surface and the image-side surface thereof are aspheric, and the image-side surface of the eighth lens element has at least one reflection point. An air gap in a paraxial region is located between every two lens elements of the photographing optical lens system that are adjacent to each other. The invention also discloses an image capturing device comprising the image capturing lens groups and an electronic device comprising the image capturing device.
本发明揭露一种影像撷取镜片组、取像装置及电子装置,影像撷取镜片组由物侧至像侧依序包含第一透镜群、第二透镜群与第三透镜群。第一透镜群包含第一透镜与第二透镜。第二透镜群包含第三透镜、第四透镜与第五透镜。第三透镜群包含第六透镜、第七透镜与第八透镜。第一透镜具有正屈折力。第七透镜物侧表面与像侧表面皆为非球面。第八透镜像侧表面于近光轴处为凹面,其物侧表面与像侧表面皆为非球面,其像侧表面具有至少一反曲点。第三透镜群的任两相邻透镜间于光轴上皆具有一空气间隔。本发明还公开具有上述影像撷取镜片组的取像装置及具有取像装置的电子装置。
