Abstract

An optical imaging lens is provided. The optical imaging lens includes sequentially from an object side to an image side along an optical axis: a first lens with a positive refractive power; a second lens with a negative refractive power; a third lens with a refractive power, an object side surface of the third lens being a convex surface, an image side surface of the third lens being a concave surface; a fourth lens with refractive power, an object side surface of the fourth lens being a convex surface, an image side surface of the fourth lens being a concave surface a fifth lens with a negative refractive power, an object side surface of the fifth lens being a convex surface, an image side surface of the fifth lens being a concave surface; and a sixth lens with a refractive power.
