Embodiment Construction

[0117] The optical imaging system group includes ten lenses, and the ten lenses are a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, and a seventh lens in sequence along the optical path from the object side to the image side. lens, eighth lens, ninth lens, and tenth lens. The ten lenses respectively have an object-side surface facing the object-side direction and an image-side surface facing the image-side direction.

[0118] The first lens can have a positive refractive power; thereby, it can provide the main converging ability, so as to effectively compress the space of the optical imaging system group, so as to meet the requirement of miniaturization. The object-side surface of the first lens can be a convex surface near the optical axis; thereby, the angle between the light rays and the lens surface can be slowed down to avoid total reflection.

[0119] The second lens can have a negative refractive power; thereby, the aberrations gen...

Abstract

The invention discloses an optical image system group, which comprises ten lenses. The ten lenses are sequentially a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, a seventh lens, an eighth lens, a ninth lens and a tenth lens from the object side to the image side along an optical path. Each of the ten lenses has an object-side surface facing the object-side direction and an image-side surface facing the image-side direction. The second lens element has negative refractive power. The tenth lens has negative refractive power, and at least one of the object-side surface of the tenth lens and the image-side surface of the tenth lens has at least one inflection point. When specific conditions are met, the optical image system group can meet the requirements of miniaturization and high imaging quality at the same time. The invention also discloses an image capturing device with the optical image system group and an electronic device with the image capturing device.

Description

technical field [0001] The invention relates to an optical imaging system group, an imaging device and an electronic device, in particular to an optical imaging system group and an imaging device suitable for electronic devices. Background technique [0002] With the improvement of semiconductor process technology, the performance of electronic photosensitive elements has been improved, and the pixel size can be smaller. 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 it is difficult for the existing optical lens to achieve a balance among the requirements of imaging quality, sensitivity, aperture size, volume or viewing angle, the present invention provides an optical lens to meet the requirements.
