Example Embodiment

[0067] [Example 1]

[0068] Please refer to figure 1 , Shows a schematic structural diagram of the imaging lens of Embodiment 1. It can be seen from the figure that the imaging lens of this embodiment includes an aperture 10, a first lens 11, a second lens 12, a third lens 13, a fourth lens 14, and a fifth lens 15 which are sequentially arranged along the optical axis from the object side to the image side. Each of the sixth lens 16 and the seventh lens 17 has an object side facing the object side and an image side facing the image side, and both the object side and the image side of each lens are aspherical. The first lens 11 has a positive refractive power, the object side surface is convex at the near optical axis, and the image side surface is concave at the near optical axis. The second lens 12 has a positive refractive power, the object side surface is convex at the near optical axis, and the image side surface is convex at the near optical axis. The third lens 13 has a n...

Abstract

The invention discloses an image pickup lens which is of a seven-piece type lens structure. Both a second lens and a fifth lens have positive refraction power; both a third lens and a sixth lens havenegative refraction power; an image side surface of a first lens is a concave surface at a position near an optical axis; an object side surface of the third lens is a concave surface at a position near the optical axis; an object side surface of the fifth lens is a concave surface at a position near the optical axis; an image side surface of a seventh lens is a concave surface at a position nearthe optical axis; and image side surface of the seventh lens is provided with at least one inflection point. By adoption of a reasonable surface shape structure of each lens and optimal range combination of optical parameters of each lens, the image pickup lens can have high imaging quality; and by reasonably defining a ratio of a sum of thickness of the third lens and a fourth lens to a spacing distance from the third lens to the fourth lens on the optical axis, the lenses can be relatively uniformly distributed so as to benefit collocation among the lenses. The image pickup lens disclosed bythe invention has the characteristics of large aperture, high pixel, high resolution, excellent field-of-view angle and the like. The invention further discloses electronic equipment.

Description

technical field [0001] The invention relates to the technical field of optical imaging devices, in particular to a camera lens. The invention also relates to an electronic device. Background technique [0002] With the rapid upgrading of related consumer electronic products such as smart phones, portable computers and tablet devices, the market has higher and higher requirements for the quality of optical imaging lenses of electronic products. With the improvement of semiconductor manufacturing technology, the pixel size of the photosensitive device has been reduced. Correspondingly, the imaging lens group is gradually developing into the high-pixel field, so the requirements for its imaging quality are also increasing. [0003] Traditional lenses mounted on portable products mostly use three-element or four-element lens structures. As the market’s requirements for lens pixels and imaging quality continue to rise, existing optical camera lenses can no longer meet higher-lev...
