Abstract
The present invention provides an optical imaging lens. The optical imaging lens comprises a lens barrel and several lens elements positioned therein. Each lens element has a lens portion and a peripheral portion formed around the lens portion and extending to the rim. The lens portion is formed with an object-side surface facing to the object side and an image-side surface facing to the image side for passing the light. One of the lens elements is an embedded lens element. The radius from the center to the rim of the embedded lens element is smaller than that of another lens element adjacent to the embedded lens element and thus the rim of the embedded lens element is embedded in the peripheral portion of the adjacent lens element.
