Abstract

The invention discloses an optical system for photographing, which comprises eight lenses, and the eight lenses are sequentially a first lens, a second lens, a third lens, a fourth lens, a fifth lens, and a sixth lens from the object side to the image side. lens, the seventh lens and the eighth lens. The eight lenses respectively have object-side surfaces facing the object-side direction and image-side surfaces facing the image-side direction. The first lens has positive refractive power. The fifth lens has positive refractive power. The object-side surface of the seventh lens is convex at the near optical axis. The image-side surface of the eighth lens is concave at the near optical axis. At least one surface of at least one lens in the imaging optical system has at least one critical point at off-axis. When certain conditions are met, the optical system for imaging can meet the needs of miniaturization and high imaging quality at the same time. The invention also discloses an image pickup device with the above optical system for imaging and an electronic device with the image pickup device.

Description

technical field [0001] The invention relates to an optical system for imaging, an imaging device and an electronic device, in particular to an optical system for imaging and an imaging 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.
