Problems solved by technology

However, the existing miniaturized optical imaging lenses still have problems such as small imaging size and large lens thickness, which usually cannot meet the requirements of small lens thickness while ensuring large image surface characteristics
Moreover, in a dark environment, the optical imaging lens does not have enough light, which leads to noise in night scene imaging

Abstract

The invention discloses an optical imaging lens, which sequentially comprises a first lens with focal power, a second lens with focal power, a third lens with positive focal power, a fourth lens withnegative focal power, a fifth lens with positive focal power and a sixth lens with focal power from an object side to an image side along an optical axis, wherein the object side surface of the firstlens is a concave surface, the maximum field angle FOV of the optical imaging lens meets the condition that FOV is larger than 90 degrees and smaller than 120 degrees, and the half ImgH of the diagonal length of the effective pixel area on the imaging surface of the optical imaging lens, the total effective focal length f of the optical imaging lens and the entrance pupil diameter EPD of the optical imaging lens satisfy the following conditional expressions: ImgH is more than 4.5 mm, f / EPD is less than 2, and f / ImgH is more than or equal to 0.9.

Description

technical field [0001] The present application relates to the field of optical elements, in particular, to an optical imaging lens. Background technique [0002] With the rapid development and manufacture of smart terminals such as smartphones, drones, and smart home monitoring equipment, the market has higher and higher requirements for the imaging quality and appearance design of optical imaging lenses. However, existing miniaturized optical imaging lenses still have problems such as small imaging size and large lens thickness, and usually cannot meet the requirements of small lens thickness while ensuring large image surface characteristics. Moreover, in a darker environment, the amount of light passing through the optical imaging lens is insufficient, resulting in noise in night scene imaging. [0003] How to make an optical imaging lens with a smaller size meet the characteristics of large image area, ultra-thin, and good imaging quality is one of the problems that man...
