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 present application discloses an imaging lens, which has a total effective focal length f and an entrance pupil diameter EPD, and includes a first lens, a second lens, a third lens, a fourth lens, The fifth lens, the sixth lens and the seventh lens, wherein the first lens and the sixth lens all have positive refractive power; the second lens, the third lens, the fifth lens and the seventh lens all have positive refractive power or negative light power; and the fourth lens has negative power, the object side is concave and the image side is convex. The total effective focal length f of the imaging lens and the entrance pupil diameter EPD of the imaging lens satisfy f / EPD≤1.7.

Description

technical field [0001] The present invention relates to a camera lens, and more particularly, the invention relates to a camera lens including seven 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 components, high...
