See full text

An annular optical 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 optical component includes multiple stripe-shaped structures disposed 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, and 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.
