Embodiment Construction

[0019] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention 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 invention, not to limit the present invention.

[0020] like figure 1 As shown, a high-pixel imaging optical system, along the optical axis from the object plane to the image plane 9 at least includes: a first lens 1, a second lens 2, a third lens 3, a fourth lens 4, a fifth lens 5, The sixth lens 6 and the seventh lens 7; the optical system satisfies the following conditions:

[0021] (1) -0.25

[0022] (2) 0

[0023] (3) 0.25

[0024] (4) 0.05

[0025] Wherein, f is the focal length of the entire optical system, f1 is the focal length of the first lens 1, f5 is the focal...

Abstract

The embodiment of the invention discloses a high-pixel camera shooting optical system. The high-pixel camera shooting optical system at least comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens and a seventh lens in sequence from an object surface to an image surface along the optical axis. The optical system meets the following conditions: (1) f / f1 is more than -0.25 and less than -0.1; (2) f / f5 is more than 0 and less than 0.3; (3) f / fI is more than 0.25 and less than 0.45; (4) f / fII is more than 0.05 and less than 0.6. On the other hand, the embodiment of the invention further provides a camera lens. According to the embodiment of the invention, the seven lenses are used in total and the quantity of the lenses is few, so that the structure is simple; furthermore, with the adoption of optical conditions met by the optical system or the camera lens, the optical system or the camera lens has the good properties of ultra-wide angle, large aperture, low chromatic aberration, high imaging pixel and the like.

Description

Technical field: [0001] The invention relates to an optical system and a lens applied thereto, in particular to a high-pixel imaging optical system and lens suitable for aerial monitoring and distance measurement of equipment such as unmanned aerial vehicles and aerial cameras. Background technique: [0002] Existing optical systems or lenses, especially an optical system or lens suitable for aerial monitoring and distance measurement of drones, aerial cameras and other equipment, have the defects of a large number of lenses, complex structures, and insufficiently clear imaging. Invention content: [0003] In order to overcome the problems of a large number of lenses, complex structures, and unclear imaging in existing optical systems or lenses, an embodiment of the present invention provides a high-pixel imaging optical system on the one hand. [0004] A high-pixel imaging optical system, which sequentially includes at least a first lens, a second lens, a third lens, a fo...
