Abstract

The optical imaging lens sequentially comprises a first lens, a second lens, a third lens and a fourth lens from an object side to an image side along an optical axis, a second lens; a third lens; the fourth lens has negative focal power; a fifth lens element; and a sixth lens. The distance TTL from the object side surface of the first lens to the imaging surface of the optical imaging lens along the optical axis and half ImgH of the length of a diagonal line of an effective pixel area on the imaging surface meet TTL / ImgHlt; and 1.3. The aperture number Fno of the optical imaging lens meets the following formula: Fnolt; 1.8).

Description

technical field [0001] The present application relates to the field of optical elements, more specifically, to an optical imaging lens. Background technique [0002] At present, the demand for taking pictures in the mobile phone market continues to increase. The main cameras of mainstream mobile phone flagships have basically reached more than 48 million pixels, and they mostly use six or seven lens structures. This is also the development trend of high-end camera phones in the future. As we all know, the larger the pixel, the larger the image surface. Moreover, on the basis of ensuring performance, the optical total length of the lens should be as small as possible. These are technical challenges faced by lens manufacturers. Therefore, the current market needs an optical imaging lens with the characteristics of large aperture, small FNO, ultra-thin and good imaging quality, so as to better meet the needs of manufacturers of smart devices such as mobile phones.
