Abstract

The present application discloses an optical imaging lens, which sequentially includes from the object side to the image side along the optical axis: a first lens with a focal power; a second lens with a focal power, the object side is a convex surface, and the image side is a a convex surface; a third lens having optical power; a fourth lens having optical power; a fifth lens having optical power; and a sixth lens having optical power. Half the Semi-FOV of the maximum field of view of the optical imaging lens satisfies: 45°<Semi-FOV<60°. The aperture number Fno of the optical imaging lens satisfies: Fno<1.8. The distance TTL from the object side of the first lens to the imaging surface of the optical imaging lens along the optical axis and the half ImgH of the diagonal length of the effective pixel area on the imaging surface satisfy: TTL / ImgH<1.4. The distance T34 between the third lens and the fourth lens on the optical axis and the distance T56 between the fifth lens and the sixth lens on the optical axis satisfy: 0.5<T34 / T56<2.0.

Description

technical field [0001] The present application relates to the field of optical components, and more particularly, to an optical imaging lens. Background technique [0002] With the continuous development of portable electronic products such as smart phones, portable electronic devices with high imaging quality are more and more popular. On the one hand, due to the miniaturization trend of portable electronic devices, higher and higher requirements have been placed on the miniaturization of the imaging lenses used together with them. The total length of the imaging lens is limited, which makes the design of the imaging lens more difficult. On the other hand, with the improvement of the performance of the photosensitive coupling element (CCD) or the complementary metal oxide semiconductor element (CMOS) and the reduction of the pixel size, higher requirements are also put forward for the imaging lens used in combination. [0003] Therefore, in order to better meet the market...
