Problems solved by technology

[0004] Usually, the resolution of the lens can be improved by increasing the number of lenses, but the volume and weight of the corresponding lens will increase, which is not conducive to the miniaturization of the lens and will increase the manufacturing cost
Under normal circumstances, in order to meet miniaturization, the resolution of the lens will be greatly affected when the total optical length of the lens is compressed

Abstract

The invention discloses an optical lens which comprises first to fifth lenses from the object side to the image side successively along the optical axis. The second, fourth and fifth lenses may have negative focal power, the third lens may have positive focal power, the object side surfaces of the first, second and fifth lenses may be concave surfaces respectively, the image side surfaces of the same may be convex surfaces respectively, and the third lens can be glued to the fourth lens.

Description

technical field [0001] The present application relates to an optical lens, and more particularly, the present application relates to an optical lens including five lenses. Background technique [0002] As pixel requirements for imaging devices (eg, cameras) gradually increase, the corresponding chip size also increases, resulting in an increase in the overall size of the lens. At the same time, in some special applications, such as the nighttime use of the vehicle lens, in order to improve the nighttime use of the lens, it is usually necessary to increase the aperture of the lens, which will also lead to an increase in the aperture of the lens. [0003] At the same time, considering factors such as aesthetics, the less exposed part of the lens installed in the vehicle is required, the better, which requires the size of the front end of the lens to be smaller. At the same time, the requirements for lens resolution are getting higher and higher, especially for lenses involvin...
