| 摘要 |
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).
