Abstract
The application provides an optical lens which is composed of eight lenses and sequentially comprises, along an optical axis from an object side to an imaging surface, a first lens with negative optical power, the image side being concave; a second lens with negative optical power, the object side being convex near the optical axis, and the image side being concave; a third lens with negative optical power, the object side being concave near the optical axis, and the image side being concave; a fourth lens with positive optical power, the object side being convex, and the image side being convex; a fifth lens with negative optical power, the object side being convex, and the image side being concave; a sixth lens with positive optical power, the object side being convex, and the image side being concave; a seventh lens with negative optical power, the object side being convex, and the image side being concave; and an eighth lens with positive optical power, the object side being convex. The optical lens provided by the application can reduce aberration, improve imaging quality, and make the lens have one or more advantages such as a large field of view, a large aperture, miniaturization, high imaging quality and the like.
