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 element1including a first optical component10and a second optical component20coupled to the first optical component10, shape accuracy of the second optical component20is improved to prevent reduction in optical performance. A ring member (106) is placed on a peripheral portion of a lens surface (10b) of the first optical component (10), the ring member (106) having a height h1from the lens surface (10b) substantially uniform in a circumferential direction of the first optical component (10).
