Abstract

The invention discloses an optical imaging lens. The optical imaging lens sequentially comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens from an objectside to an image side along an optical axis, wherein the first lens has negative power and the image side of the first lens is a concave surface; the second lens has focal power; the third lens has positive power and the image side of the third lens is a convex surface; the fourth lens has focal power; the fifth lens has positive power and the image side of the fifth lens is a convex surface; thesixth lens has negative power and the object side of the sixth lens is a concave surface; and the spacing distance T56 of the fifth lens and the sixth lens on the optical axis, the spacing distance T34 of the third lens and the fourth lens on the optical axis and the spacing distance T45 of the fourth lens and the fifth lens on the optical axis meet the relational expression: 1.0<T56 / (T34+T45) / 6<=3.0.

Description

technical field [0001] The present application relates to an optical imaging lens, and more particularly, to an optical imaging lens including six lenses. Background technique [0002] With the development of science and technology, portable electronic products are gradually rising, and portable electronic products with camera functions are more and more favored by people. Therefore, the market demand for imaging lenses suitable for portable electronic products is gradually increasing. On the one hand, since portable electronic products such as smart phones tend to be miniaturized, the overall length of the lens is limited, thereby increasing the difficulty of lens design. On the other hand, as the performance and size of common photosensitive elements such as photosensitive coupling device (CCD) or complementary metal oxide semiconductor device (CMOS) are improved and the size is reduced, the number of pixels of the photosensitive element is increased and the size of the pi...
