Problems solved by technology

[0003] At present, due to the miniaturization trend of electronic products, the total length of the lens is limited, which makes the lens design more difficult. The size of the image area of ​​the traditional supporting lens is usually only about 1 / 3 inch, and it is difficult to take into account the ultra-thin and large image area while miniaturizing and high resolution

Abstract

The invention discloses an optical imaging lens. From an object side to an image side in sequence along an optical axis, the optical imaging lens includes: a first lens with focal power, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, a seventh lens, and an eighth lens, wherein the first lens has negative focal power; the third lens and the sixth lens have positive focal power; the object side of the fourth lens is a convex side, and the image side of the fourth lens is a concave side; the object side of the fifth lens is the convex side, and the image side of the fifthlens is the concave side; and the distance on the optical axis TTL from the object side of the first lens to the image side of the optical imaging lens and half of a diagonal ImgH of an effective pixel area on the image side of the optical imaging lens meets that TTL / ImgH is less thanor equal to1.25.

Description

technical field [0001] The present application relates to an optical imaging lens, and more particularly, to an optical imaging lens including eight lenses. Background technique [0002] In recent years, with the popularity of electronic products such as mobile phones and tablet computers, people have higher and higher requirements for portable and thinner electronic products; and under the trend of popularization of large-size and high-pixel CMOS chips, the Various aspects of the supporting optical lens have also put forward increasingly stringent requirements, such as requiring it to have a larger imaging size. [0003] At present, due to the miniaturization trend of electronic products, the total length of the lens is limited, which makes the lens design more difficult. The size of the image surface of the traditional supporting lens is usually only about 1 / 3 inch, and it is difficult to take into account the ultra-thin and large image surface while miniaturizing and hig...
