Abstract
An optical lens and imaging equipment including the optical lens are disclosed. The optical lens can sequentially comprise a first lens, a second lens, a third lens, a fourth lens, a fifth lens and asixth lens from the object side to the image side along the optical axis. The first lens can have negative focal power, the object side surface of the first lens is a convex surface, and the image side surface of the first lens is a concave surface; the second lens can have positive focal power, the object side surface of the second lens is a concave surface, and the image side surface is a convexsurface; the third lens can have positive focal power, and the object side surface and the image side surface of the third lens are convex surfaces; the fourth lens can have positive focal power, andthe object side surface and the image side surface of the fourth lens are convex surfaces; the fifth lens can have negative focal power, and the object side surface and the image side surface of thefifth lens are concave surfaces; and the sixth lens can have positive focal power, and the object side surface and the image side surface of the sixth lens are convex surfaces. According to the optical lens provided by the invention, at least one of the beneficial effects of high resolution, miniaturization, small front-end aperture, large aperture, small CRA, low cost, long rear focal length andthe like can be realized.
Description
technical field [0001] The present application relates to an optical lens and an imaging device including the optical lens, more particularly, the present application relates to an optical lens including six lenses and an imaging device. Background technique [0002] With the development of science, more and more fields need to use optical lenses as "eyes", such as vehicle, monitoring, projection, industrial fields, etc. [0003] With the growth of demand and the development of technology, the performance requirements of optical lenses are also getting higher and higher, especially the pixel requirements of optical lenses are very high, and the size of chips is also increased accordingly, resulting in the The size has also increased, and the cost has increased. [0004] For some applications with limited installation positions, such as optical lenses for vehicle applications, because they need to be installed in the car, the installation position is limited, such as the inn...
