Abstract
An optical imaging lens includes a lens barrel, a plurality of lens elements, and a light-shielding element. The lens barrel has a mounting portion. Each of the lens elements has an object-side mechanic surface facing an object side and an image-side mechanic surface facing an image side. A material of the light-shielding element is metal or plastic. The optical imaging lens satisfies the following conditional expressions depending on the material of the light-shielding element: −200 μm<RA1−RA2≤450 μm, or −200 μm≥RA1−RA2≥−300 μm. The mounting portion can carry the light-shielding element and has a carrying surface facing the image side. There is a minimum distance between the carrying surface and an optical element closest to the carrying surface in a direction parallel to an optical axis. The minimum distance is less than or equal to 5,000 μm. Furthermore, other optical imaging lenses are provided.
