Abstract
The present invention relates to composite optical elements, and particularly to a composite optical element in which second and third optical components are coupled to a first optical component. The present invention is advantageous in enhancing optical properties. A composite optical element () includes first, second and third optical components (). The first optical component () has a lens surface (). The second optical component () is coupled to the first optical component () at the lens surface () and has a lens surface () at a side opposite to a first coupling surface () at which the second optical component () is coupled to the first optical component (). The third optical component () is coupled to the second optical component () at the lens surface () and has a lens surface () at a side opposite to a second coupling surface () at which the third optical component () is coupled to the second optical component (). The lens surface () partially has a first uneven region (). The lens surface () partially has a third uneven region (). The lens surface () partially has a third uneven region ().
