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 () includes a first optical component () and a second optical component (). The first optical component () is made of first glass and has a lens surface (). The second optical component () is made of a material different from the first glass, is coupled to the first optical component () at a lens surface (), and has a lens surface () at a side opposite to the first coupling surface (). The lens surface () partially has a first uneven region (). The lens surface () partially has a second uneven region ().
