摘要： An optical imaging lens sequentially including a first lens element to a ninth lens element arranged in sequence from an object side to an image side along an optical axis is provided. Each of the first lens element to the ninth lens element includes an object-side surface facing the object-side surface and allowing imaging rays to pass through and an image-side surface facing the image-side and allowing the imaging rays to pass through. Lens elements of the optical imaging lens are only the nine lens elements described above, wherein the second lens element has negative refracting power, the fourth lens element has negative refracting power, an optical axis region of the object-side surface of the seventh lens element is concave, and an optical axis region of the image-side surface of the ninth lens element is concave.

摘要： The present invention provides an optical imaging lens. The optical imaging lens comprises six lens elements positioned in an order from an object side to an image side. Through controlling convex or concave shape of surfaces of the lens elements and designing parameters satisfying at least one inequality, the optical imaging lens may present a great field of view with smaller surface area of the front side of the optical imaging lens.

摘要： Present embodiments provide for an optical imaging lens. The optical imaging lens includes a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element and a sixth lens element 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 and designing parameters satisfying at least two inequalities, the optical imaging lens shows better optical characteristics, increases the effective focal length and narrows the angle of view while the total length of the optical imaging lens is shortened.
