Abstract

The present invention discloses an optical imaging lens which sequentially comprises from an object side to an image side along an optical axis: a first lens with focal power; a second lens with positive focal power; a third lens with negative focal power; a fourth lens with focal power; a fifth lens with focal power; a sixth lens with focal power; a seventh lens with focal power; and an eighth lens with focal power, wherein the object side surface of the eighth lens is a concave surface. The total effective focal length f of the optical imaging lens and the entrance pupil diameter EPD of the optical imaging lens meet the condition that f / EPD is less than or equal to 1.6; and the distance TTL from the object side surface of the first lens to the imaging surface of the optical imaging lens on the optical axis and half ImgH of the diagonal length of an effective pixel area on the imaging surface meet the condition that TTL / ImgH is less than or equal to 1.6.

Description

technical field [0001] The present application relates to the field of optical elements, in particular, to an optical imaging lens. Background technique [0002] In recent years, with the development of photography technology for portable electronic products such as smart phones, mobile phone lenses with high image quality are more and more favored by consumers. However, due to the natural limitation of the small space of the smartphone, it is more difficult for the lens of the mobile phone to obtain high-quality images in complex light environments. Therefore, how to improve the shooting quality of mobile phone lenses in complex light environments while satisfying the existing mobile phone space has become one of the problems that many lens designers need to solve urgently. Contents of the invention [0003] One aspect of the present application provides such an optical imaging lens, the optical imaging lens includes in sequence from the object side to the image side alo...
