Embodiment Construction

[0099] The optical image lens group includes nine lenses, and the nine lenses are sequentially the first lens, the second lens, the third lens, the fourth lens, the fifth lens, the sixth lens, and the seventh lens along the optical path from the object side to the image side. lens, the eighth lens and the ninth lens. Wherein, the nine lenses respectively have an object-side surface facing the object-side direction and an image-side surface facing the image-side direction.

[0100] The first lens has positive refractive power. In this way, the main convergence capability can be provided to effectively compress the space of the optical image lens group to meet the requirement of miniaturization.

[0101] The second lens has a negative refractive power; thereby, the aberration generated by the first lens can be balanced, thereby correcting spherical aberration and chromatic aberration. The object-side surface of the second lens can be convex at the near optical axis, and the im...

Abstract

The invention discloses an optical image lens assembly, an image capturing device and an electronic device. The optical image lens assembly comprises nine lenses. The nine 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 and a ninth lens from the object side to the image side along an optical path. Each of the nine lenses has an object-side surface facing the object-side direction and an image-side surface facing the image-side direction. The first lens element has positive refractive power. The second lens element has negative refractive power. The image-side surface of the ninth lens element is concave in a paraxial region, and the image-side surface of the ninth lens element has at least one inflection point. When specific conditions are met, the optical image lens 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 lens group and an electronic device with the image capturing device.

Description

technical field [0001] The invention relates to an optical image lens group, an image capturing device and an electronic device, in particular to an optical image lens group and an image capturing device suitable for the electronic device. 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 existing optical lens is difficult 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.
