COMPOSITE OPTICAL ELEMENT
First Claim
1. A composite optical element, comprising:
- a first optical component having a first optical functional surface and made of first glass; and
a second optical component made of a material different from the first glass, coupled to the first optical component at the first optical functional surface, and having a second optical functional surface at a side opposite to a first coupling surface of the second optical component at which the second optical component is coupled to the first optical component,wherein the first and second optical functional surfaces partially have first and second uneven regions, respectively.

Abstract
The present invention relates to composite optical elements, and particularly to a composite optical element including a first optical component and a second optical component coupled to the first optical component.
The present invention is advantageous in enhancing optical properties.
A composite optical element (1) includes a first optical component (10) and a second optical component (20). The first optical component (10) is made of first glass and has a lens surface (12). The second optical component (20) is made of a material different from the first glass, is coupled to the first optical component (10) at a lens surface (22), and has a lens surface (22) at a side opposite to the first coupling surface (21). The lens surface (12) partially has a first uneven region (12a). The lens surface (22) partially has a second uneven region (22a).
