Abstract
A lens includes: a lens surface region having a lens surface that condenses incident light; and a non-lens surface region in which the lens surface is nonexistent. The lens surface includes: a first lens surface that is a convex lens surface and is configured as a convex curved surface having a vertex; and a second lens surface that is an aspheric surface and has a different curvature from the first lens surface. An axis of a principal ray defined with respect to the second lens surface is non-coaxial with an axis of a principal ray defined with respect to the first lens surface.

A lens comprising:
- a lens surface region having a lens surface configured to condense incident light;
- and a non-lens surface region in which the lens surface is nonexistent,
- the lens surface including:
- a first lens surface that is a convex lens surface, the first lens surface being configured as a convex curved surface having a vertex;
- and
- a second lens surface that is an aspheric surface, the second lens surface having a different curvature from the first lens surface,
- an axis of a principal ray defined with respect to the second lens surface being non-coaxial with an axis of a principal ray defined with respect to the first lens surface.
