Embodiment Construction

[0026] 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.

[0027] like figure 1 As shown, a low-distortion optical system includes in sequence from the object plane to the image plane 8 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 lenses6.

[0028] The object plane side of the first lens 1 is a convex surface, the image plane side is a concave surface, and its focal power is negative;

[0029] The object plane side of the second lens 2 is a convex surface, the image plane side is a concave surface, and its focal power is negative;

[0030] The o...

Abstract

The embodiment of the invention discloses a low-distortion optical system which at least successively comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens from an object surface to an image surface along an optical axis. On the other hand, the embodiment of the invention further provides a lens. The low-distortion optical system disclosed by the embodiment of the invention is mainly composed of the six lenses, the number of lenses is small, the structure is simple, and the volume is small; and different lenses are adopted and mutually combined, and the low-distortion optical system has good optical properties such as large viewing angle, low distortion and high resolution.

Description

[0001] Technical field: [0002] The invention relates to an optical system and its applied lens, in particular to a low-distortion optical system composed of six lenses and its applied lens. [0003] Background technique: [0004] The patent with the publication number CN101587231B discloses a vehicle-mounted front-view lens. The lens uses six all-glass lenses, which are heavy in quality, high in cost, and have defects such as small field of view and large distortion. [0005] Invention content: [0006] In order to overcome the problems of small field of view and large distortion existing in existing optical systems or lenses, the embodiments of the present invention provide a low-distortion optical system on the one hand. [0007] The low-distortion optical system includes: a first lens, a second lens, a third lens, a fourth lens, a fifth lens, and a sixth lens in order along the optical axis from the object plane to the image plane; [0008] The object plane side of the f...
