Abstract

The invention discloses an optical imaging camera lens. The camera lens comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, a seventh lens and an eighth lens in sequence from the object side to the image side along the optical axis. The first lens has positive focal power, and the object side is the convex side; the second lens has negative focal power;the second lens has positive focal power; the fourth lens has positive focal power or negative focal power, the object side is the concave side, and the image side is the convex side; the fifth lens has positive focal power or negative focal power; the sixth lens has positive focal power or negative focal power, and the object side is the convex side; the seventh lens has positive focal power or negative focal power; the eighth lens has negative focal power.

Description

technical field [0001] The present application relates to an optical imaging lens, and more specifically, the present application relates to an optical imaging lens including eight lenses. Background technique [0002] In recent years, with the rapid development of portable electronic products with imaging functions, the requirements for miniaturized optical systems are also increasing. The photosensitive element of the general imaging lens is mainly a photosensitive coupling device (CCD) or a complementary metal oxide semiconductor element (CMOS). With the advancement of semiconductor process technology, the number of pixels of the photosensitive element increases and the size of the pixel decreases. Therefore, higher requirements are put forward for the high imaging quality and miniaturization of the matching imaging lens. [0003] As the requirements for miniaturized imaging lenses increase in terms of pixels and imaging quality, imaging lenses are gradually developing i...
