Abstract
The present invention belongs to a technical field related to a composite optical element including a first optical component and a second optical component coupled to the first optical component. In a composite optical elementincluding a first optical componentand a second optical componentcoupled to the first optical component, shape accuracy of the second optical componentis improved to prevent reduction in optical performance. A ring member () is placed on a peripheral portion of a lens surface () of the first optical component (), the ring member () having a height hfrom the lens surface () substantially uniform in a circumferential direction of the first optical component ().
