Problems solved by technology

As far as the seven-piece lens structure is concerned, the distance between the object side of the first lens and the imaging surface on the optical axis is large, which is not conducive to the thinning of portable electronic products such as mobile phones and digital cameras. Therefore, it is extremely necessary to develop Optical imaging lenses with large angles and short system lengths

Abstract

The invention discloses an optical imaging lens. The first, second, third, fourth, fifth, sixth and seventh lenses are sequentially included along an optical axis from the object side to the image side. Each lens has an object side and an image side. The object side of the third lens has a convex portion located in the vicinity of the circumference. The object side surface of the fifth lens has a convex portion located near the optical axis and a concave portion located near the circumference. The object side of the sixth lens has a concave portion located in the vicinity of the circumference. The optical imaging lens includes only the first lens to the seventh lens with refractive power.

Description

technical field [0001] The invention relates to an optical lens, and in particular to an optical imaging lens. Background technique [0002] In recent years, the popularity of portable electronic products such as mobile phones and digital cameras has led to the vigorous development of imaging module related technologies. This imaging module mainly includes components such as optical imaging lenses, module holder units and sensors. Mobile phones The thinner and lighter trend of digital cameras also makes the miniaturization of image modules more and more demanding. With the technological advancement and size reduction of charge coupled device (CCD) and complementary metal oxide semiconductor (CMOS), the optical imaging lens installed in the camera module also needs to be reduced in size , but the optical performance of the optical imaging lens is also necessary to take into account. As far as the seven-piece lens structure is concerned, the distance between the object side ...
