Abstract
An imaging lens assembly has an optical axis, and includes a plurality of optical elements. The optical axis passes through the optical elements, and the optical elements include a radial reduction lens element and a radial reduction light blocking element. The radial reduction lens element includes an optical effective portion and a peripheral portion. The peripheral portion is disposed around the optical effective portion along a circumferential direction of the optical axis. The radial reduction light blocking element includes a central opening and a radial reduction part. The optical axis passes through the central opening. The radial reduction part is reduced towards the optical axis along a direction vertical to the optical axis, so that the central opening is non-circular. The radial reduction part includes a plurality of light blocking structures. The light blocking structures are arranged along the direction vertical to the optical axis.
