Optical lens module with plastic barrel, imaging apparatus including same module and electronic device including same apparatus

摘要

An optical lens module includes a lens assembly and a plastic barrel. The lens assembly includes a plurality of lens elements and is disposed in the plastic barrel. The plastic barrel includes an object-end portion, an image-end portion, an outer tube portion, an inner tube portion and at least one reflection reduction area. The image-end portion includes an image-end opening. The inner tube portion includes a plurality of parallel inner surfaces and a plurality of inclined inner surfaces, wherein the parallel inner surfaces are parallel to the central axis, and each of the inclined inner surfaces has an angle with the central axis. The reflection reduction area is disposed on one of the inclined inner surfaces closest to the image-end opening, wherein the reflection reduction area and the plastic barrel are integrally formed by an injection molding method.
