Problems solved by technology

Although this type of lens can meet the miniaturization requirements, it cannot guarantee the imaging quality of the lens in the case of insufficient light, so the lens with an aperture number Fno of 2.0 or above can no longer meet the higher-level imaging requirements

Abstract

The invention discloses an optical imaging lens. The optical imaging lens comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens in order from an object side to an image side along an optical axis. The first lens and the fifth lens have positive power. The second lens, the third lens and the fourth lens have positive power or negative power. The object side of the first lens and the image side of the fifth lens are convex sides. The image side of the second lens, the object side of the sixth lens and the image side of the sixth lens are concave sides. According to the total effective focal length f of the optical imaging lens and the entrance pupil diameter EPD of the optical imaging lens, f/EPD is less than or equal to 1.8.

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 six lenses. Background technique [0002] With the development of science and technology, portable electronic products gradually rise, and the portable electronic products with camera function are more favored by people, so the market demand for camera lenses suitable for portable electronic products is gradually increasing. As portable electronic products tend to be miniaturized, the total length of the lens is limited, which increases the difficulty of lens design. [0003] At the same time, with the improvement of the performance and the reduction of the size of common photosensitive elements such as photosensitive coupling device (CCD) or complementary metal oxide semiconductor element (CMOS), the number of pixels of the photosensitive element increases and the size of the pixel decreases, thereby ...
