Abstract

The invention provides an imaging lens, and the lens comprises a first lens which has positive focal power, and the surface, facing a light-emitting side, of the first lens is a concave surface; the second lens has focal power, the surface, facing the light incident side, of the second lens is a convex surface, and the surface, facing the light emergent side, of the second lens is a concave surface; the third lens has focal power; the fourth lens has negative focal power, and the surface, facing the light emitting side, of the fourth lens is a concave surface; the fifth lens has positive focal power, the surface, facing the light incident side, of the fifth lens is a convex surface, and the surface, facing the light emergent side, of the fifth lens is a convex surface; the sixth lens has negative focal power, the surface, facing the light incident side, of the sixth lens is a convex surface, and the surface, facing the light emergent side, of the sixth lens is a concave surface; wherein the half ImgH of the diagonal length of an effective pixel area on the imaging surface of the imaging lens, the entrance pupil diameter EPD of the imaging lens and the effective focal length f of the imaging lens meet the following conditions: 2.7 mmlt; imgH * EPD / flt; 5 mm. The problem that an imaging lens in the prior art is incompatible with miniaturization and high image quality is solved.

Description

Technical field [0001] The present invention relates to the technical field of optical imaging equipment, and in particular, there is a imaging lens. Background technique [0002] With the booming of smart products, the demand for the shots assembled on mobile terminals is also higher, especially in the high-end models. The large image and large aperture of the lens help achieve higher resolution and signal-to-noise ratio, and ultra-thin helps to better compatibility with the lens, which can greatly improve the imaging ability and competitive advantage of the lens. At the same time, the design lens design also proposed a higher difficult challenge. [0003] That is, there is a problem that the imaging lens in the prior art is small and high image quality is incompatible. Inventive content [0004] The primary object of the present invention is to provide an imaging lens to solve problems in which the imaging lens in the prior art is small and high image quality is not compatible...
