Abstract
The present invention relates to a composite lens and a method for manufacturing the same, particularly to a composite lens in which a second lens component is coupled to a first lens component at part of a first surface, and intends to improve optical characteristics. A composite lens () has a first lens component () and a second lens component (). The first lens component () has a first surface including a first lens surface (), a peripheral surface () surrounding the first lens surface () and a ring surface () included in the peripheral surface () and surrounding the first lens surface (), and a second lens surface () on the opposite side of the first lens surface (). The second lens component () is coupled to the first lens component () at part of the first surface surrounded by the ring surface (). The ring surface () is positioned on a portion of the first lens component protruding from a joint portion () between the first lens surface () and the peripheral surface () in a first direction from the second lens surface () to the first lens surface () along an optical axis of the first lens component () and is exposed out of the second lens component ().
