Abstract
An optical imaging lens includes, in order from an object side to an image side, an aperture, a first lens, a second lens, a third lens, a fourth lens and a fifth lens, wherein the first lens has positive refractive power and includes an object-side surface being convex; the second lens has negative refractive power and includes an object-side surface being concave; the third lens has positive refractive power and includes an object-side surface being convex and an image-side surface being convex; the fourth lens has positive refractive power and includes an object-side surface being concave and an image-side surface being convex; the fifth lens has negative refractive power and includes an object-side surface being concave. When specific conditions are satisfied, the optical imaging lens can have a compact size, high thermal endurance and good imaging qualities.
