Abstract

An optical imaging lens sequentially 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 from an object side to an image side along an optical axis. Each of the first to eighth lenses comprises an object side surface facing the object side and allowing imaging light to pass therethrough and an image side surface facing the image side and allowing imaging light to pass therethrough. The first lens has a positive refractive index. The second lens has a negative refractive index. The optical axis area of the object sidesurface of the fifth lens is a concave surface. The optical axis area of the object side surface of the sixth lens is a convex surface. The optical axis area of the image side surface of the seventhlens is a convex surface. The lens with refractive index of the optical imaging lens is only the first lens to the eighth lens. The lens of the optical imaging lens has a small aperture value, a shortsystem length and a large field angle, and can still maintain good imaging quality.

Description

technical field [0001] The invention relates to the field of optical imaging, in particular to an optical imaging lens. Background technique [0002] In recent years, the optical imaging lens has been continuously evolving, and the number of optical lenses is used to modify problems such as aberration and dispersion to achieve higher and higher imaging quality requirements. With the increase in the number of optical lenses, the larger distance on the optical axis from the object side of the first lens to the imaging surface will be unfavorable for the thinning of mobile phones, digital cameras and automotive lenses. Therefore, designing an optical imaging lens with good imaging quality, light weight and small size has always been the development goal of the design. In addition, a small aperture value is beneficial to increase the luminous flux, and a large field of view is gradually becoming a market trend. How to design an optical imaging lens with a small aperture value ...
