Abstract
A lens module includes a lens barrel, a first lens, a second lens, and a spacer. The lens barrel includes an object-side end and an image-side end opposite to the object-side end. The first lens is received in the lens barrel, and adjacent to the object-side end. The second lens is received in the lens barrel, and adjacent to the image-side end in relative to the first lens. The spacer is an annular plate, and includes an object-side surface, an image-side surface opposite to the object-side surface, and an inner sidewall. The spacer is positioned between the first lens and the second lens. The object-side surface faces the first lens, and the image-side surface faces the second lens. The intersection of the object-side surface and the inner sidewall forms a chamfer.
