Composite optical element and method for manufacturing the same

bbThe 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 element including a first optical component and a second optical component coupled to the first optical component , shape accuracy of the second optical component is 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 h from the lens surface substantially uniform in a circumferential direction of the first optical component.
