Embodiment Construction

[0115] The image capture optical system includes ten lenses, and the ten lenses are the first lens, the second lens, the third lens, the fourth lens, the fifth lens, the sixth lens, the Seventh lens, eighth lens, ninth lens and tenth lens. Wherein, the ten lenses respectively have object-side surfaces facing the object-side direction and image-side surfaces facing the image-side direction. In this way, the viewing angle and imaging surface can be increased within a limited volume, and the image quality can be improved.

[0116] The first lens has positive refractive power; thereby, it helps to compress the volume of the image capturing optical system. The object-side surface of the first lens can be convex at the near optical axis; thereby, the light of each field of view can enter the image capture optical system evenly, which helps to increase the viewing angle and improve the peripheral illumination of the imaging surface.

[0117] The image-side surface of the second len...

Abstract

The invention discloses an image capturing optical system, an image capturing device and an electronic device. The image capturing optical system includes 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 first lens element has positive refractive power. The second lens element has an image-side surface being concave in a paraxial region thereof. The tenth lens element has negative refractive power. At least one of an object-side surface and an image-side surface of at least one lens in the image capturing optical system has at least one critical point at an off-axis position. When specific conditions are met, the image capturing optical system can meet the requirements of wide viewing angle, miniaturization and high imaging quality at the same time. The image capturing device is provided with the image capturing optical system, and the electronic device is provided with the image capturing device.

Description

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