Abstract

The invention discloses an optical imaging lens. The optical imaging lens includes a first lens body, a second lens body, a third lens body, a fourth lens body, a fifth lens body and a sixth lens bodywhich are arranged along an optical axis from an object side to an image side. The first lens body has positive focal power, and the object side face of the first lens body is a convex face; the second lens body has focal power, and the image side face of the second lens body is a concave face; the third lens body has focal power, and the object side face of the third lens body is a convex face;the fourth lens body has focal power, and the object side face of the fourth lens body is a concave face; the fifth lens body has focal power; the sixth lens body has focal power, and the object sideface of the sixth lens body is a concave face; the maximum effective radius DT11 of the object side face of the first lens body and the maximum effective radius DT61 of the object side face of the sixth lens body meet the condition that DT11/DT61 is greater than 0.6 and smaller than 1.

Description

technical field [0001] The present application relates to an optical imaging lens, and more specifically, the present application relates to an optical imaging lens including six lenses. Background technique [0002] With the rapid upgrading of related consumer electronic products such as smart phones, portable computers and tablet devices, the market has higher and higher requirements for the quality of optical imaging lenses of electronic products. Not only the optical imaging lens is required to have basic performance such as high resolution and high relative brightness, but also the optical imaging lens is required to have characteristics such as telephoto. However, existing telephoto lenses usually increase the number of lenses to achieve high imaging quality, resulting in a large size, which cannot meet the current ultra-thin and miniaturized development of electronic equipment while taking into account telephoto characteristics and high imaging quality. need.
