Abstract
An optical imaging lens may include a first, a second, a third, a fourth and a fifth lens elements positioned in an order from an object side to an image side. Through designing concave and/or convex surfaces of the five lens elements, the optical imaging lens may provide improved imaging quality and optical characteristics, increased focal length of the optical imaging lens, improved assembly yield and reduced size of the imaging lens while the optical imaging lens may satisfy (T2+G23+T3+G34+T4+G45+T5)/G12≤2.700, wherein a thickness of the second lens element along the optical axis is represented by T2, a thickness of the third lens element along the optical axis is represented by T3, a thickness of the fourth lens element along the optical axis is represented by T4, a thickness of the fifth lens element along the optical axis is represented by T5, a distance from the image-side surface of the first lens element to the object-side surface of the second lens element along the optical axis is represented by G12, a distance from the image-side surface of the second lens element to the object-side surface of the third lens element along the optical axis is represented by G23, a distan…
