摘要： An imaging lens assembly includes a lens barrel, optical lens elements, an annular retaining element and a nano-microstructure. The optical lens elements include at least one optical lens element disposed in the lens barrel. The annular retaining element is physically contacted with the optical lens element, and the annular retaining element includes an object-side surface, an image-side surface, an outer diameter surface and a light-through hole. The outer diameter surface is connected to the object-side surface and the image-side surface. The light-through hole is formed by gradually tapering from the object-side surface and the image-side surface towards the optical axis. The nano-microstructure has a plurality of irregular ridged convexes. The nano-microstructure is located between a lens barrel area defined via the lens barrel and a lens element area defined via the optical lens element on a direction vertical to the optical axis.

摘要： A plastic lens element includes an optical effective portion and a peripheral portion. The peripheral portion surrounds the optical effective portion and includes a peripheral surface and an optical inspecting structure. The optical inspecting structure is disposed between the optical effective portion and the peripheral surface and includes a first optical inspecting surface and a second optical inspecting surface. The first optical inspecting surface and the second optical inspecting surface are disposed on two sides of the peripheral portion respectively and correspond to each other.
