Abstract

The invention discloses an imaging lens. The imaging lens comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens sequentially from an object side and an image side along an optical axis, wherein the first lens has positive focal power, and the object side surface of the first lens is a convex surface; the second lens has negative focal power; the third lens has negative focal power, the object side surface of the third lens is a convex surface, and the image side surface of the third lens is a concave surface; the fourth lens has focal power; the fifth lens has positive focal power; the sixth lens has focal power, and the object side surface of the sixth lens is a concave surface; any two of the first lens, the second lens, the third lens, the fourth lens, the fifth lens and the sixth lens are glued to form a glued lens group; and the combined focal length f12 of the first lens and the second lens, the curvature radius R1 of the object side surface of the first lens and the curvature radius R4 of the image side surface of the second lens meet the condition that 2.0<f12 / R1+f12 / R4 <3.3.

Description

technical field [0001] The present application relates to an imaging lens, and more particularly, the present application relates to an imaging lens including six lenses. Background technique [0002] In recent years, the combined zoom solution of wide-angle + telephoto dual-camera lens has gradually emerged, and has gradually become the mainstream production direction of many mobile phone manufacturers. The combined zoom idea of ​​the wide-angle + telephoto dual-camera lens is: use two lenses with different focal lengths, the wide-angle lens with a wide viewing angle can "see" very wide, but "see" distant objects clearly, and the telephoto lens with a narrow viewing angle Although the "seeing" range of the focal lens is not large, the "seeing" is farther and clearer. The combination of wide-angle and telephoto lenses can achieve relatively smooth zooming through lens switching and fusion algorithms when taking pictures. The practical application of this zoom solution has ...
