Abstract: A six-piece wide-angle lens module includes, from an object side to an image side, a first lens group, an aperture and a second lens group. The first lens group consists of a negative first lens, a negative second lens and a positive third lens, each lens having an object side surface facing the object side and an image side surface facing the image side, the first lens is a meniscus lens having a convex object side surface, the second lens has a concave image side surface, the third lens has a convex object side surface. The second lens group consists of a positive fourth lens, a negative fifth lens and a positive sixth lens, the fourth lens is a biconvex lens, the fifth lens has a concave image side surface, the sixth lens has a convex object side surface, the second lens group has a positive focal length.

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 arranged 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 surface towards the object side and a concave surface towards the image side. The second lens is a positive lens with a convex surface towards the object side. The third lens is a positive biconvex lens, and the fourth lens is a negative biconcave lens. The fifth lens has a convex surface towards the object side.

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.

Abstract: A five-piece wide-angle lens module includes a first lens, a second lens, a third lens, a stop, a fourth lens and a fifth lens, which are sequentially arranged from an object side to an image side. The first lens has a negative refractive power, a convex surface on the object side, and a concave surface on the image side. The second lens has a negative refractive power and two concave surfaces on both sides respectively. The third lens has a positive refractive power. The fourth lens has a positive refractive power and two convex surfaces on both sides respectively. The fifth lens has a negative refractive power. To provide good image quality, the five-piece wide-angle lens module satisfies the following relationships: ?0.6<f2/f3<?0.3, and ?0.25<f4/f5<?0.15.
