Problems solved by technology

However, with the continuous development of portable electronic products such as smart phones, higher requirements are put forward for the camera lens, especially for situations such as insufficient light (such as rainy days, dusk, etc.), hand shake, etc., so the aperture number of 2.0 or above Fno has been unable to meet higher-order imaging requirements

Abstract

The invention discloses an imaging lens. The imaging lens sequentially comprises a first lens body, a second lens body, a third lens body, a fourth lens body and a fifth lens body along an optical axis from the object side to the image side. The first lens body has positive focal power, the object side face of the first lens body is a convex face, and the image side face of the first lens body is a convex face. The second lens body has negative focal power; the third lens body has positive focal power, the object side face of the third lens body is a convex face, and the image side face of the third lens body is a convex face. The fourth lens body has positive focal power, the fifth lens body has negative focal power, and the face inclination angle beta 5 of the maximum effective radius position of the object side face of the fifth lens body is larger than -20 degrees and smaller than 5 degrees.

Description

technical field [0001] The present application relates to an imaging lens, and more particularly, the present application relates to an imaging lens including five lenses. Background technique [0002] In recent years, with the development of science and technology, portable electronic products have gradually emerged, and portable electronic products with camera functions have been more favored by people. Therefore, the market demand for camera lenses suitable for portable electronic products has gradually increased. As portable electronic products tend to be miniaturized, the total length of the lens is limited, which increases the difficulty of lens design. The photosensitive element of the currently commonly used camera lens is generally a CCD (Charge-Coupled Device, photosensitive coupling element) or a CMOS (Complementary Metal-Oxide Semiconductor, complementary metal oxide semiconductor element). With the improvement of performance and size reduction of CCD and CMOS c...
