摘要： An optical imaging lens includes a plurality of lens elements arranged in the given order from an object side to an imaging side. Each of the lens elements has a refracting power, an object-side surface facing toward the object side and an image-side surface facing toward the image side. The lens elements include a first lens element closest to the object side, a second lens element second closest to the object-side, a third lens element having a positive refracting power, and a fourth lens element having its object-side and image-side surfaces being aspheric. The object-side surface of the first lens element has a concave portion in the vicinity of the optical axis. The third lens element has at least one of the object-side and image-side surfaces being aspheric.

摘要： An imaging lens includes plastic-made first, second, third, and fourth lens elements arranged in the given order from an object side to an imaging side. The first lens element has a positive focusing power and is biconvex. The second lens element has a negative focusing power, is biconcave, and has an abbe number not greater than 30. The third lens element has a positive focusing power and has a convex imaging-side surface facing toward the imaging side. The fourth lens element has an imaging-side surface formed with a concave area in a vicinity of an optical axis of the fourth lens element. The imaging lens further includes an aperture stop disposed between the first and second lens elements.

摘要： Present embodiments provide for a mobile device and an optical imaging lens thereof. The optical imaging lens comprises five lens elements positioned sequentially from an object side to an image side. Through controlling the convex or concave shape of the surfaces and/or the refracting power of the lens elements and designing an equation, the optical imaging lens shows better optical characteristics and the total length of the optical imaging lens is shortened.
