Abstract

The present application discloses an optical lens. The optical lens may include: a first lens, a second lens, a third lens, a fourth lens, a fifth lens, and a sixth lens in order from the object side to the image side along the optical axis. and seventh lens. Wherein, the first lens can have negative refractive power, its object side is convex, and the image side is concave; the second lens can have negative refractive power, its object side is convex, and the image side is concave; the third lens can have negative power, its object side and image side are both concave; the fourth lens may have positive power, its object side is convex; and the seventh lens may have positive power, its object side and image side are convex, wherein , the fifth lens and the sixth lens can be cemented to form a cemented lens. According to the optical lens of the present application, at least one beneficial effect of miniaturization, high resolution, low cost, good temperature performance, and small diameter at the front end can be realized.

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] The current automotive industry's requirements for automotive lenses involve miniaturization, low cost, and high resolution. At the same time, because the driving environment of the car is relatively changeable, the lens mounted outside the car must have the ability to maintain a high resolution in various harsh environments. [0003] However, with the gradual use of large-size, high-pixel chips, the original pixels of vehicle lenses can no longer match these chips, and it is urgent to develop new higher-pixel lenses to replace existing low-pixel lenses on the market. In order to achieve a higher pixel of the lens, it is necessary to increase the number of lenses or use aspherical lenses, which are limited by the two requirements of low cost and miniaturization. [0004] In...
