Abstract:
A miniature image pickup lens includes a first lens, a second lens, a third lens, an aperture, 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 meniscus lens with negative refractive power and has a convex side facing the object side. The first lens has at least an aspheric side. The second lens is a biconvex lens with positive refractive power. The third lens is a biconcave lens with negative refractive power. The fourth lens is a biconvex lens with positive refractive power and has at least an aspheric side. The fifth lens has a negative refractive power.
