Abstract

The present application discloses an optical lens, which sequentially includes from the object side to the image side along the optical axis: a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens and The seventh lens, wherein the first lens is a meniscus lens with negative power, its object side is convex, and its image side is concave; the second lens has negative power, its object side is concave, and its image side is concave Concave surface; the third lens has positive power, its object side is convex, and its image side is convex; the fourth lens has positive power, its object side is convex, and its image side is convex; the fifth lens has negative power, its The object side is concave, and the image side is concave; the sixth lens has positive refractive power, and the object side is convex, and the image side is convex; the seventh lens is a meniscus lens, and the object side is convex, and the image side is concave. The optical lens according to the present application has the characteristics of high resolution, for example, up to 12M and above, miniaturization, large aperture, low cost and small CRA.

Description

technical field [0001] The present application relates to an optical lens, and more particularly, the present application relates to an optical lens including seven lenses. Background technique [0002] With the popularization of unmanned driving technology, the requirements for the pixel of the car lens as the eyes of the car are getting higher and higher. At present, the car lens with megapixels has gradually become popular, and is developing towards the trend of tens of millions of high-definition pixels. [0003] In order to achieve high resolution of the lens, it can usually be achieved by increasing the number of lenses, but this will affect the miniaturization of the lens. Moreover, in order to be used in low-light environments, the 10-megapixel lens needs a larger aperture; in order to avoid color cast when matching the 10-megapixel chip, a smaller CRA is required. [0004] Therefore, it is necessary to design a lens with high resolution and high imaging quality at...
