Abstract

An optical imaging lens comprises an aperture, a first lens, a second lens, a third lens, a fourth lens, and a fifth lens arranged in sequence from an object side to an image side. The first lens is made of glass and is a convex-concave lens having positive refractive power. The convex surface faces the object side, and the concave surface faces the image side. The second lens is a convex-concave lens having negative refractive power with the convex surface facing the object side and the concave surface facing the image side. The third lens is a convex-concave lens having positive refractive power with the convex surface facing the image side and the concave surface facing the object side. The fourth lens is made of glass having a refractive index greater than or equal to 1.7 and is a convex-concave lens having positive refractive power with the convex surface facing the image side and the concave surface facing the object side. The fifth lens having refractive power that gradually converts from negative refractive power to positive refractive power from the center toward the edge thereof.
