Abstract:
Disclosed is a low-cost, compact image pickup lens for a solid-state image pickup element. The image pickup lens includes, in the order from an object side, a first lens L1, which has a convex surface facing the object side on an optical axis and has a positive refractive power; a second lens L2, which has a concave surface facing an image side on the optical axis and has a negative refractive power; a third lens L3, which has a positive refractive power and has aspheric surfaces on the object side and the image side; a fourth lens L4, which has a convex surface facing the image side on the optical axis, has a positive refractive power, and has a meniscus shape; and a fifth lens L5, which has a concave surface facing the image side on the optical axis, has a negative refractive power, and has a meniscus shape.
