Optical imaging lens

Abstract

The present invention discloses an optical imaging lens. The optical imaging lens comprises a first lens, a second lens, a third lens and a fourth lens which are sequentially distributed along an optical axis from one object side to one image side; and the first lens, the second lens, the third lens and the fourth lens satisfy an relational expression that ALT / AAG<=1.25. The optical imaging lens of the present invention is used for optical photography imaging. The length of the optical imaging lens can be decreased under a condition that excellent optical performance is maintained.

Description

technical field [0001] The invention relates to an optical imaging lens, in particular to a four-chip optical imaging lens. Background technique [0002] The specifications of consumer electronic products are changing with each passing day, and the pursuit of lightness, thinness and compactness has never slowed down. Therefore, the specifications of key components of electronic products such as optical lenses must continue to improve in order to meet the needs of consumers. In addition to the image quality and volume, the most important characteristics of an optical lens are increasing the field of view angle. The application of optical lenses is not limited to shooting images and videos, but also needs such as environmental monitoring and driving record photography. [0003] However, optical lens design does not simply reduce the proportion of a lens with good imaging quality to produce an optical lens with both image quality and miniaturization.
