Abstract
This invention provides an optical lens comprising eight lenses, arranged sequentially along the optical axis from the object side to the image plane: a first lens with negative optical power, having a convex object side and a concave image side; a second lens with positive optical power, having a convex object side and a convex image side; a third lens with positive optical power, having a convex object side and a convex image side; a fourth lens with negative optical power, having a concave object side; a fifth lens with positive optical power, having a convex object side and a convex image side; a sixth lens with negative optical power, having a concave object side and a concave image side; a seventh lens with positive optical power, having a convex object side and a convex image side; and an eighth lens with negative optical power, having a concave object side. The optical lens provided by this invention can improve the image quality of an optical lens, reduce aberrations, and enhance the overall image quality.
