Abstract
An optical imaging lens module is provided. The optical imaging lens module may include a lens barrel and an optical imaging lens. The optical imaging lens may include a plurality of lens elements engaged with the lens barrel in an order from an object side to an image side along an optical axis. A first lens element is the lens element closest to the object side in the plurality of lens elements. The first lens element may include an optical effective portion and an optical ineffective portion surrounding the optical effective portion. The optical effective portion may include an object-side surface facing toward the object side and allowing imaging rays to pass through as well as an image-side surface facing toward the image side and allowing the imaging rays to pass through. A border around the object-side surface may have an extension surface extending from the object side toward the image side.
