Patent ID: 8111470

Claim:
A composite lens comprising a first lens component and a second lens component coupled to part of a first surface of the first lens component, wherein the first lens component has the first surface including a first lens surface, a peripheral surface surrounding and joined to the first lens surface and a ring surface included in the peripheral surface and surrounding the first lens surface, and a second lens surface on the opposite side of the first lens surface, the second lens component has an outer surface on the opposite side of the first lens surface, is coupled to the first lens component at part of the first surface surrounded by the ring surface, and the ring surface is positioned on a portion of the first lens component protruding from a joint portion between the first lens surface and the peripheral surface in a first direction from the second lens surface to the first lens surface along an optical axis of the first lens component and is exposed out of the second lens component, wherein the outer surface has a curved surface shape, wherein the ring surface includes a first ring surface portion and a second ring surface portion positioned closer to the joint portion than the first ring surface portion in the first direction, the first and second ring surface portions being arranged in a circumferential direction of the ring surface, and the first ring surface portion is exposed out of the second lens component and at least part of the second ring surface portion is coupled to the second lens component.
