Abstract

The present invention discloses an imaging optical lens assembly. The optical imaging lens assembly includes five lens elements, which are, in order from an object side to an image side: a first lenselement, a second lens element, a third lens element, a fourth lens element and a fifth lens element. The first lens element with positive refractive power has an object-side surface being convex in aparaxial region thereof. The third lens element has negative refractive power. The fifth lens element has negative refractive power.

Description

technical field [0001] The invention relates to an imaging optical lens group, an image capturing device and an electronic device, in particular to an imaging optical lens group and an image capturing device suitable for an electronic device. Background technique [0002] With the improvement of semiconductor process technology, the performance of electronic photosensitive elements has been improved, and the pixels can reach a smaller size. Therefore, optical lenses with high imaging quality have become an indispensable part. With the rapid development of science and technology, the application range of electronic devices equipped with optical lenses is wider, and the requirements for optical lenses are also more diverse. Because the previous optical lens is not easy to balance among the requirements of imaging quality, sensitivity, aperture size, volume or viewing angle, so the present invention provides an optical lens to meet the requirements.
