摘要： A plastic barrel includes an object-end portion, an image-end portion, an inner tube portion and a plurality of protrusions. The object-end portion includes an outer object-end surface, an object-end hole and an inner annular object-end surface. One side of the inner annular object-end surface is connected to the outer object-end surface and surrounds the object-end hole. The image-end portion includes an outer image-end surface, an image-end opening and an inner annular image-end surface. The inner annular image-end surface is connected to the outer image-end surface and surrounds the image-end opening. The inner tube portion connects the object-end portion and the image-end portion and includes a plurality of inclined surfaces. The protrusions are disposed at least on one of the inner annular object-end surface, the inner annular image-end surface and the inclined surfaces, wherein the protrusions are regularly arranged around the central axis of the plastic barrel.

摘要： A plastic lens element includes an optical effective region and a peripheral region. The peripheral region is circularly disposed on a periphery of the optical effective region, and the peripheral region includes a protrusive structure, an indented shape and a drafting part. The protrusive structure is disposed on an outer diameter surface and adjacent to an annular lateral surface. The indented shape is dented from the outer diameter surface towards the optical effective region. The drafting part is raised from a base surface towards the direction away from an optical axis, and the drafting part has a top surface and a bottom surface via the section, wherein the top surface and the bottom surface are arranged along an extending direction parallel to the optical axis, and a conical surface is located between the top surface and the bottom surface.

摘要： An annular optical element includes an outer annular surface, an inner annular surface, a first side surface, a second side surface and a plurality of strip-shaped wedge structures. The outer annular surface surrounds a central axis of the annular optical element and includes at least two shrunk portions. The first side surface connects the outer annular surface and the inner annular surface. The second side surface connects the outer annular surface and the inner annular surface, wherein the second side surface is disposed correspondingly to the first side surface. The strip-shaped wedge structures are disposed on the inner annular surface, wherein each of the strip-shaped wedge structures is disposed along a direction from the first side surface towards the second side surface and includes an acute end and a tapered portion connecting the inner annular surface and the acute end.

摘要： An annular light trapping component includes an inner surface, an outer surface, an object-side surface and an image-side surface. The inner surface includes multiple L-shaped annular grooves. The annular light trapping component includes multiple stripe-shaped structures in the L-shaped annular grooves. The L-shaped annular grooves include an object-side L-shaped annular groove closest to the object-side surface and an image-side L-shaped annular groove closest to the image-side surface. A bottom diameter of the image-side L-shaped annular groove is larger than a bottom diameter of the object-side L-shaped annular groove. Each L-shaped annular groove includes a first side and a second side located between the object-side surface and the image-side surface. The stripe-shaped structures are disposed on the first side or the second side. A degree of inclination between the first side and the central axis is larger than a degree of inclination between the second side and the central axis.
