Problems solved by technology

[0002] With the development of society, electronic products such as mobile phones and tablets have become indispensable tools in people's lives. In order to be able to adapt to these electronic products, while ensuring the image quality, mobile phone lenses are gradually becoming smaller and thinner. development direction, which makes the design more difficult
In addition, the performance improvement and size reduction of the image sensor also make the design freedom of the corresponding lens less and less, increasing the design difficulty

Abstract

The invention discloses an optical imaging lens. The lens sequentially comprises a diaphragm, a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens from an object side to an image side along an optical axis; the first lens has focal power; the second lens has focal power, and the object side surface of the second lens is a concave surface; the third lens has positive focal power; the fourth lens has negative focal power, and the object side surface of the fourth lens is a convex surface; the fifth lens has focal power; and the sixth lens has focal power. The distance TTL from the object side surface of the first lens to the imaging surface of the optical imaging lens along the optical axis and the half ImgH of the diagonal length of an effective pixel area on the imaging surface of the optical imaging lens meet the condition that TTL / ImgH is smaller than 1.5. The effective focal length f4 of the fourth lens and the effective focal length f1 of the first lens meet the condition that f4 / f1 is larger than -9.0 and smaller than -3.5.

Description

technical field [0001] The present application relates to the field of optical elements, more specifically, to an optical imaging lens. Background technique [0002] With the development of society, electronic products such as mobile phones and tablets have become indispensable tools in people's lives.
