Abstract

The invention discloses an optical imaging lens. The optical imaging lens comprises a first lens with focal power, a second lens with focal power, a third lens with focal power, a fourth lens with focal power, a fifth lens with focal power, a sixth lens with focal power, a seventh lens with focal power and an eighth lens with focal power from the object side to the image side along an optical axisin sequence. The object side face of the first lens is a convex face, and the image side face of the first lens is a concave face. The object side face of the second lens is a convex face, and the image side face of the second lens is a concave face. The object side face of the eighth lens is a concave face. The maximum half-field angle Semi-FOV of the optical imaging lens and the effective focallength f8 of the eighth lens meet the formula: 2.4 millimeters<=tan(Semi-FOV)*|f8|<3.5 millimeters.

Description

technical field [0001] The present application relates to the field of optical elements, in particular, to an optical imaging lens. Background technique [0002] In recent years, with the continuous development of camera equipment, it has been popularized and applied in many fields. At the same time, the market has higher and higher requirements for imaging quality of camera equipment. For example, as the main camera of a mobile terminal device, the optical imaging lens presents a development trend of large image area, large aperture, and ultra-thin, which poses new challenges for optical system design. Among the layers of challenges in optical system design, resolution is an important part. The resolution performance of the optical imaging lens has a great influence on the imaging quality of the camera equipment. Improving the resolution of optical imaging lenses helps to improve the imaging quality of camera equipment. Therefore, an optical imaging lens with high resol...
