Abstract:
A miniature image pickup lens includes a first lens, a second lens, an aperture, a third lens, a fourth lens, and a fifth lens in sequence along an optical axis from an object side to an image side. The first lens is a negative meniscus lens with a convex aspheric surface toward the object side and a concave aspheric surface toward the image side. The second lens has both aspheric surfaces including a convex surface toward the object side. The third lens is a positive biconvex lens. The fourth lens is a positive biconvex lens. The fifth lens is a negative lens with a concave surface toward the object side.
