Abstract

See full text

An optical lens, comprising a first to an eighth lens (L1, L2, L3, L4, L5, L6, L7, L8) coaxially arranged in sequence along the direction of transmission of an incident light ray. The first lens (L1) is a negative meniscus lens, and the curved surface of the first lens (L1) is convex to the object side; the second lens (L2) is a positive biconvex lens; the third lens (L3) is a negative biconcave lens; the fourth lens (L4) is a positive meniscus lens and the curved surface of the fourth lens (L4) is convex to the object side; the fifth lens (L5) is a negative meniscus lens and the curved surface of the fifth lens (L5) is convex to the object side; the sixth lens (L6) is a positive biconvex lens; the seventh lens (L7) is a negative meniscus lens and the curved surface of the seventh lens (L7) is convex to the image side; and the eighth lens (L8) is a negative meniscus lens and the curved surface of the eighth lens (L8) is convex to the image side; the fourth lens (L4) and the fifth lens (L5) are respectively positioned on the two sides of an optical diaphragm (200) of the optical lens; the second lens (L2), the third lens (L3), and the fourth lens (L4) form a first cemented lens set; and the fifth lens (L5), the sixth lens (L6), and the seventh lens (L7) form a second cemented lens set. The present optical lens has a relatively large field-of-view, and obtains high-definition zero distortion imaging results.
