Abstract:
1. An imaging lens formed of only two lens components, arranged along an optical axis in order from the object side, as follows: a first lens component; a stop; and a second lens component; wherein the two object-side lens surfaces and the two image-side lens surfaces of the two lens components are aspheric; the first lens component has negative refractive power, the lens surface on the object side of the first lens component is convex near the optical axis, and the lens surface on the image side of the first lens component is concave near the optical axis; the second lens component has positive refractive power and the lens surface on the image side of the second lens component is convex near the optical axis; and the following conditions are satisfied: where D is the distance along the optical axis from the object-side lens surface of the first lens component to the image-side lens surface of the second lens component, D h z
