Abstract

The present invention provides an image-taking optical lens, an image-taking device and an electronic device, wherein the image-taking optical lens includes seven lenses, and the seven lenses are in sequence from the object side to the image side: a first lens; a first lens Two lenses; a third lens; a fourth lens; a fifth lens; a sixth lens; and a seventh lens. When certain conditions are met, the imaging optical lens can simultaneously have high imaging quality, large aperture and telephoto capability.

Description

technical field [0001] The present invention relates to an image-taking optical lens and an image-taking device, in particular to an image-taking optical lens and an image-taking device applicable to electronic devices. 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. [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. Because the optical lenses in the past are not easy to meet the requirements of imaging quality, sensitivity, aperture size, volume or viewing angle, etc. Therefore, the present invention provides an optical lens to meet the requirements.
