Abstract

An optical photographing system includes a plurality of lens elements which include, in order from an object side to an image side: a first lens element, a second lens element and a last lens element.There is no additional lens element disposed between the first lens element and the second lens element, and there is no additional lens element disposed between the last lens element and an image surface. The first lens element has a first refractive surface, a first reflective surface, a second reflective surface and a second refractive surface. The first reflective surface faces toward the object side, and the second reflective surface faces toward the image side. At least one lens element of the optical photographing system has at least one lens surface with at least one inflection point.

Description

technical field [0001] The invention relates to an optical photography system and an electronic device, in particular to an optical photography system 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. Contents of the invention [0004] The invention provides an optical ...
