Abstract

The invention discloses an optical lens. In one embodiment, the optical lens comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens and a seventh lens in sequence from an object side to an image side along an optical axis, wherein the first lens is of negative power, 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 second lens is of negative power, the object side face of the second lens is a convex face, and the image side face of the second lens is of a concave face; the third lens is of negative power, the object side face of the third lens is a concave face, and the image side face of the third lens is a convex face; the fourth lens is of positive power, the object side faceof the fourth lens is a convex face, and the image side face of the fourth lens is a concave face; the fifth lens and the sixth lens are glued together; the seventh lens is of positive power, and theobject side face and the image side face of the seventh lens are convex faces respectively. Through the optical lens disclosed by the invention, the resolution can be promoted while miniaturization is guaranteed through reasonable combination of the lenses.

Description

technical field [0001] The present application relates to the field of optics, in particular to an optical lens, and more specifically to an optical lens including seven lenses. Background technique [0002] With the popularity of vehicle lenses from the beginning of use to today, people's requirements for lenses have changed from simple imaging at the beginning to several megapixels now. [0003] Improving the imaging quality of the lens is generally achieved by using more lenses or by replacing ordinary spherical lenses with aspherical surfaces. Because of the application field, the vehicle lens must be miniaturized and small in size. [0004] However, in the existing technology, the measures taken to meet the increasingly higher imaging requirements often contradict the miniaturization requirements, and the measures to improve the resolution will also increase the cost significantly from another level. [0005] Therefore, lenses that can achieve miniaturization, low cos...
