Abstract

The present application discloses an optical lens, and the optical lens may include: a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens and Seventh lens. The first lens can have positive refractive power, and its object side is convex, and the image side is concave; the second lens can have negative refractive power, and its object side and image side are concave; the third lens can have positive refractive power, and Both the object side and the image side are convex; the fourth lens can have positive power, the object side is concave, and the image side is convex; the fifth lens can have positive power, and the object side and the image side are convex; the sixth The lens may have negative optical power with a convex object side and concave image side; and the seventh lens may have negative optical power with a concave object side. According to the optical lens of the present application, at least one beneficial effect of miniaturization, high resolution, small aperture at the front end, high relative illuminance, matching large-size chips, etc. can be realized.

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...
