Abstract

A photographing optical lens system includes seven lens elements which are, in order from an object side to an image side: a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element, a sixth lens element and a seventh lens element. Each of the seven lens elements has an object-side surface facing toward the object side and an image-side surface facing toward the image side. The object-side surface of the first lens element is convex in a paraxial region thereof. The seventh lens element has negative refractive power. The object-side surface of the seventh lens element is concave in a paraxial region thereof. At least one of all lens surfaces of the seven lens elements is aspheric and has at least one inflection point. When specific conditions are met, the photographing optical lens can meet the requirements of miniaturization and large aperture at the same time. The invention also provides an image capturing unit with the photographing optical lens and electronic device with the image capturing unit.

Description

technical field [0001] The invention relates to an optical lens for imaging, an image pickup device and an electronic device, in particular to an optical lens for imaging and an image pickup device suitable for the electronic device. Background technique [0002] With the improvement of semiconductor 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. [0003] 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. Since the conventional optical lens is not easy to achieve a balance among requirements such as imaging quality, sensitivity, aperture size, volume, or viewing angle, the present invention provides an optical lens to meet the requirements.
