Abstract

The present application discloses an optical lens, and the optical lens may sequentially include: a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens along the optical axis from the object side to the image side . 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 concave, and the image side is convex; the third lens can have positive optical power. Power, the object side is convex, and the image side is concave; the fourth lens can have positive power, and the object side and image side are both convex; the fifth lens can have negative power, and the object side is concave, like The sides are convex; and the sixth lens may have negative power, with both the object and image sides being concave. According to the optical lens of the present application, beneficial effects such as miniaturization, small diameter at the front end, and high pixels 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 six lenses. Background technique

[0002] Due to the limitation of application, the vehicle lens needs to be installed in a fixed position of the car, and the lens should not be too large, which will affect the appearance of the car. Therefore, the miniaturization of the vehicle lens is very important. In recent years, the development of vehicle lens has gradually improved, and the market's requirements for vehicle lens have gradually increased; at the same time, the overall development trend also makes it very urgent to increase the pixels of vehicle lens. High-pixel car lenses that match large chips are the market trend of the entire car lens. Generally speaking, as the size of the chip increases, the total length of the lens will also increase proportionally, which seriously affects the installation and use of the...
