Abstract

The present application discloses an optical lens. In one embodiment, the optical lens includes in sequence from the object side to the image side along the optical axis: a first lens, a second lens, a third lens, a fourth lens and a fifth lens, wherein the first lens has a negative power, and the object side and image side of the first lens are both concave; the second lens has positive power, and has a meniscus shape with a convex surface facing the image side; the third lens has positive power, and the third lens has Both the object side and the image side are convex; the fourth lens has positive power, and the object side and the image side of the fourth lens are convex; and the fifth lens has negative power. By using the optical lens according to the present application, the overall optical system can be made compact through reasonable collocation of the lenses, thereby meeting the miniaturization requirement.

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 comprising five lenses. Background technique [0002] In recent years, with the rapid growth of the advanced driver assistance system (ADAS) market, the requirements for the performance of the vehicle lens, which is an important part of it, are also increasing. [0003] Large field of view and high pixels are already necessary conditions for this type of lens. However, with the improvement of the resolution and the increase of the field of view, the volume of the lens must also increase. [0004] In addition, from the perspective of economic benefits, under the premise of ensuring performance, low-cost solutions are the development trend. In addition, due to the space limitation of the installation location, it is also necessary to ensure that the front end of the lens has a small aperture for easy installation. [0005]...
