Abstract

The application provides an optical imaging lens group. The optical imaging lens group 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 along an optical axis from an object side to an image side. The first lens has a focal power, the second lens has a positive focal power, the third lens has a focal powerand an image side surface thereof is a convex surface, the fourth lens has a negative focal power, the fifth lens has a focal power, the sixth lens has a focal power and an object side surface thereofis a concave surface and an image side surface thereof is a convex surface, the seventh lens has a positive focal power, and the eighth lens has a focal power.

Description

technical field [0001] The present application relates to an optical imaging lens set, more specifically, the present application relates to an optical imaging lens set including eight lenses. Background technique [0002] In recent years, with the improvement of the requirements for the software and hardware of mobile phones, higher and higher requirements have been put forward for the imaging quality of the imaging lens mounted on the mobile phone. In addition to the basic parameters such as high pixel and high resolution, mobile phone lenses are increasingly required to have the characteristics of ultra-thin, large aperture, and wide field of view. Therefore, the targeted development of these characteristics has become the main focus of mobile phone lens design. [0003] In theory, adding multiple lenses to enable the system to have more space and degrees of freedom to find the optimal solution is one of the most efficient ways to improve the imaging quality of the optic...
