Abstract

The invention discloses optical lenses. The optical lenses may comprise a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens and a seventh lens in order from an objectside to an image side along an optical axis; the first lens may have a positive refractive power, with an object side surface being a convex surface and an image-side surface being a concave surface;the second lens may have a negative refractive power, with an object side surface and an image side surface being concave surfaces; the third lens may have a positive refractive power, with an objectside surface and an image side surface being convex surfaces; the fourth lens may have a positive refractive power, with an object side surface being a concave surface and an image side surface beinga convex surface; the fifth lens may have a positive refractive power, with an object side surface and an image side surface being convex surfaces; the sixth lens may have a negative refractive power,with an object side surface being a convex surface and an image side surface being a concave surface; and the seventh lens may have a negative refractive power, with an object side surface being a concave surface. According to the optical lenses disclosed by the invention, at least one of the beneficial effects of miniaturization, high resolution, small caliber at a front end, high relative illumination and matching with a large-size chip can be implemented.

Description

technical field [0001] The present application relates to an optical lens, and more particularly, the present application relates to an optical lens including seven lenses. Background technique [0002] At present, lenses are widely used in vehicle-assisted driving systems, and even for automatic driving. As the application environment changes, the quality requirements of the lens are also increasing. The pixel requirements of the optical lens are getting higher and higher, so that the size of the chip increases accordingly, and the size of the entire lens increases accordingly. Especially for automotive optical lenses, high pixels and large chips must become the main development direction. However, for applications where the installation position of automotive lenses is limited, how to achieve miniaturization on the basis of ensuring high pixels and large chips has become a key issue. Contents of the invention [0003] The present application provides an optical lens t...
