An optical imaging lens may include a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element, a sixth lens element, a seventh lens element and an eighth lens element positioned in an order from an object side to an image side. Through designing concave and/or convex surfaces of the lens elements, the optical imaging lens may increase resolution, enlarge aperture stop and image height, and maintain well image quality.

Optical imaging lens

An optical imaging lens, including a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element, a sixth lens element, a seventh lens element, and an eighth lens element sequentially along an optical axis from an object side to an image side, is provided. Each lens element includes an object-side surface facing the object side and allowing imaging rays to pass through and an image-side surface facing the image side and allowing the imaging rays to pass through. The second lens element has negative refracting power. An optical axis region of the object-side surface of the third lens element is concave. An optical axis region of the image-side surface of the fourth lens element is concave. An optical axis region of the object-side surface of the fifth lens element is concave. The seventh lens element has positive refracting power.

An optical imaging lens includes first to seventh lens elements sequentially arranged along an optical axis from an object side to an image side, and each including an object-side surface facing toward the object side and allowing an imaging ray to pass through and an image-side surface facing toward the image side and allowing the imaging ray to pass through. The first lens element has positive refracting power. The fourth lens element has positive refracting power. A periphery region of the object-side surface of the fourth lens element is convex. An optical axis region of the object-side surface of the sixth lens element is convex. An optical axis region of the image-side surface of the sixth lens element is concave. An optical axis region of the object-side of the seventh lens element is concave. Lens elements of the optical imaging lens are only the seven lens elements described above.

The present invention provides an optical imaging lens. The optical imaging lens comprises eight lens elements positioned in an order from an object side to an image side. Through controlling the convex or concave shape of the surfaces of the lens elements, the optical imaging lens may enlarge aperture stop and image height and sustain relative illumination.
