Optical imaging lens

Abstract

The invention discloses an optical imaging lens, which comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens and a seventh lens arranged from an object side to an image side. Through the concave and convex arrangements of the surfaces of the seven lenses, the overall length of the optical imaging lens is shortened, and the imaging quality and optical performances are also considered.

Description

technical field [0001] The invention relates to an optical imaging lens, in particular to a seven-chip optical imaging lens. Background technique [0002] As the specifications of consumer electronic products are changing with each passing day, and the pace of consumers' pursuit of thinner, lighter and smaller products has not slowed down, the specifications of key components of electronic products such as optical lenses are bound to continue to improve in order to meet the needs of consumers. The most important characteristics of optical lenses are nothing more than imaging quality and volume. For the current seven-piece imaging lens, because the distance between the side of the first lens and the imaging surface on the optical axis is very large, it is not conducive to mobile phones and mobile phones. Thinning of digital cameras. [0003] In view of this, it is necessary to take into account the imaging quality and performance of the lens while pursuing the thinning of th...
