Abstract

The present application discloses an optical lens, which sequentially includes a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens along an optical axis from the object side to the image side. Wherein, the first lens has negative refractive power, and its image side is concave; the second lens has positive refractive power, its object side is convex, and the image side is concave; the third lens has positive refractive power, and its object side is concave, The image side is convex; both the fourth lens and the sixth lens have positive power; and the fifth lens has negative power.

Description

technical field [0001] The present application relates to an optical lens, and more particularly, the present application relates to an optical lens including six lenses. Background technique [0002] As the requirements for camera pixels increase, the corresponding chip size also increases, resulting in an increase in the size of the entire lens. [0003] However, for some applications where the installation position is limited, it is necessary to use a small size lens to meet the installation requirements. For example, a vehicle-mounted lens that needs to be installed in the car has a limited installation position, and a special lens design is required to meet the small size requirement. [0004] In addition, because vehicle-mounted lenses are widely used in vehicle-mounted assisted driving systems, they are used to assist the driver in driving, and even for automatic driving. Due to considerations of safety and other aspects, there are high requirements for the image cl...
