Problems solved by technology
[0002] With the development of optical lens and chip technology, the conventional wide-angle lens can no longer meet the application in some occasions due to the limitation of its field of view, such as the field of security and monitoring lights. The conventional lens is limited by the field of view of the lens , there will be a monitoring dead angle, and the fisheye lens can meet the requirements of a large observation range and can solve this problem

Embodiment Construction
[0047] In order to make the technical problems, technical solutions and beneficial effects solved by the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.
[0048] The application is achieved through the following technical solutions:
[0049] Such as Figure 1 to Figure 6 As shown, the super wide-angle fisheye lens optical system includes in sequence from the object plane to the image plane 12 along the optical axis: a first lens 1, a second lens 2, a third lens 3, a fourth lens 4, a fifth lens 5, and a first lens. Six lenses 6, the seventh lens 7, the eighth lens 8, the ninth lens 9, the tenth lens 10, and the eleventh lens 11; the object plane side of the first lens 1 is a convex surface, and the...

The application relates to a lens, in particular to an ultra-wide fisheye lens optical system. The ultra-wide fisheye lens optical system 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, a fifth lens, a sixth lens, a seventh lens, an eighth lens, a ninth lens, a tenth lens and an eleventh lens. By reasonably collocating the first to eleventh lenses and making use of the structure characteristic of each lens, the field angle of the lens achieves 265 degrees in the ultra-wide range, but the F-Theta distortion is less than 11%. Thus, the edge deformation of a shot picture is relatively small, and the picture is closer to reality. Chromatic aberration is well corrected, and high imaging quality is achieved. An effect of tens of millions of pixels can be achieved. The quality of imaging is improved.
Description
【Technical field】 [0001] The present application relates to a lens, in particular to an ultra-wide-angle fisheye lens optical system. 【Background technique】 [0002] With the development of optical lens and chip technology, the conventional wide-angle lens can no longer meet the application in some occasions due to the limitation of its field of view, such as the field of security and monitoring lights. The conventional lens is limited by the field of view of the lens , there will be a monitoring dead angle, and the fisheye lens can meet the requirements of a large observation range and can solve this problem. Generally, a fisheye lens with an angle of view exceeding 140° is a fisheye lens, and a fisheye lens with an angle of view exceeding 180° is an ultra-wide-angle fisheye lens optical system. Currently, the largest ultra-wide-angle fisheye lens optical system on the market can reach 220° or 230°. 【Content of invention】 [0003] In order to provide a fisheye lens with ...
