Abstract
An optical imaging module includes an optical imaging lens assembly, a light path folding element and a light blocking element. The optical imaging lens assembly includes at least one optical lens element. The light path folding element has an incident surface, an emitting surface and at least one optical reflecting surface, and the light path folding element is disposed on an image side of the optical imaging lens assembly. The light blocking element is disposed on one of the optical lens element and the light path folding element, and the light blocking element includes an opening hole and a light blocking surface. The light blocking surface has an anti-reflective light blocking membrane layer. A surface of the anti-reflective light blocking membrane layer has a plurality of nanostructures, and the nanostructures are arranged in an irregular form.
