Abstract
A plastic lens element includes an effective optical portion and a peripheral portion in order from an optical axis to an edge thereof. The peripheral portion includes a plurality of rib structures, wherein each of the rib structures has a strip shape in a radial direction of the optical axis, and the rib structures are arranged around the effective optical portion and indirectly connected to the effective optical portion.
Claims14
A lens module, comprising an optical lens assembly, wherein the optical lens assembly comprises at least two optical elements, one of the optical elements is a plastic lens element, and in order from an optical axis of the plastic lens element to an edge thereof, the plastic lens element comprises:
- an effective optical portion;
- and
- a peripheral portion, comprising:
- a plurality of rib structures, wherein each of the rib structures has a strip shape in a radial direction of the optical axis, and the rib structures are arranged around the effective optical portion and indirectly connected to the effective optical portion;
- and
- an object-side abutting surface disposed on a surface of the peripheral portion facing an object, wherein at least another one of the optical elements is abutted with the object-side abutting surface, the rib structures are disposed on the surface of the peripheral portion facing the object, and the rib structures are farther from the effective optical portion than the object-side abutting surface is from the effective optical portion.
