Abstract

The invention discloses an optical imaging lens, which sequentially comprises the following components from an object side to an image side along an optical axis: a first lens, a second lens, a thirdlens, a fourth lens, a fifth lens, a sixth lens and a seventh lens, wherein the first lens has an optical power, an object-side surface of the first lens is a concave surface, and an image-side surface of the first lens is a convex surface; the second lens has an optical power; the third lens has a positive optical power; the fourth lens has a negative optical power; the fifth lens has a positiveoptical power; the sixth lens has an optical power, an object-side surface of the sixth lens is a convex surface, and an image-side surface of the sixth lens is a concave surface; and the seventh lens has a negative optical power.

Description

technical field [0001] The invention relates to an optical imaging lens, in particular to an optical imaging lens including seven lenses. Background technique [0002] With the rapid development of portable electronic devices, users have increasingly stringent requirements on image quality and other photographic functions of portable electronic devices such as smart phones. Further improving the imaging quality by increasing the number of lenses is the main way to improve mobile phone imaging. However, improving the image quality simply by increasing the number of lenses is obviously not conducive to the miniaturization of the lens, and does not meet the market's demand for lightweight mobile phones. [0003] On the other hand, with the diversification of mobile phone applications, users hope to shoot more scenes in a short distance when using mobile phones to shoot. Therefore, it is necessary to provide a high-definition large image surface wide-angle lens to meet the dema...
