Abstract

The invention discloses an optical imaging lens, which sequentially comprises a first lens with positive focal power, a second lens, a third lens, a fourth lens, a fifth lens whose image side surfaceis a concave surface, a sixth lens with positive focal power, a seven lens with negative focal power, the object side surface of the seventh lens being a convex surface, and the image side surface ofthe seventh lens being a concave surface, from an object side to an image side along an optical axis. Half ImgH of the diagonal length of the effective pixel area on the imaging surface, the entrancepupil diameter (EPD) of the optical lens and the total effective focal length f of the optical imaging lens can meet the condition that ImgH * EPD/f is larger than 3.5 mm.

Description

technical field [0001] The present application relates to the field of optical components, and more particularly, to an optical imaging lens. Background technique [0002] A camera module is usually provided on a portable device such as a mobile phone, so that the mobile phone has a camera function. The camera module is usually provided with a charge-coupled device (CCD) type image sensor or a complementary metal oxide semiconductor (Complementary Metal Oxide Semiconductor, CMOS) type image sensor, and is provided with an optical imaging lens. The optical imaging lens can collect the light on the object side, and the imaging light travels along the optical path of the optical imaging lens and irradiates the image sensor, and then the image sensor converts the optical signal into an electrical signal to form image data. [0003] People are more and more fond of taking pictures with their mobile phones in daily life, and they expect mobile phones to have powerful shooting fun...
