Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0024] like figure 1 As shown, the super wide-angle spherical fisheye optical system is sequentially arranged along the optical axis from the object plane to the image plane: a first lens 1, a second lens 2, a third lens 3, a fourth lens 4, a fifth lens 5 and The sixth lens 6 .

[0025] 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;

[0026] The object plane side of the second lens 2 is a convex surface, and the image plane side is a concave surface, and its focal power is negative;

[0027] The object plane side of the third lens 3 is a convex surface, and the image plane side is a concave surface, and its focal power is negative;

[0028] The object plane side of the fourth lens 4 is a convex surface, the image plane side is a convex surface, and i...

Abstract

The ultra-wide-angle global fisheye optical system relates to the field of optical systems, and overcomes the problems of the existing fisheye optical system with a large number of lenses, a complex structure, and an aspheric design. Along the optical axis from the object plane to the image plane, there are: the first lens, the second lens, the third lens, the fourth lens, the fifth lens and the sixth lens; The surface side is convex, the image side is concave, and its power is negative; the fourth lens and the fifth lens are biconvex lenses, and their power is positive; the object side of the sixth lens is concave , the image side is convex, and its focal power is negative; the present invention is mainly composed of six spherical lenses, the number of lenses is small, the structure is simple, and the volume is miniaturized; different lenses are combined with each other and the focal power is allocated reasonably, with 190 0 Optical properties such as ultra-wide angle, low distortion and high transmission, suitable for 360 0 No dead angle security monitoring and unmanned driving and other fields.

Description

technical field [0001] The invention relates to the field of optical systems, in particular to an ultra-wide-angle spherical fisheye optical system. Background technique [0002] The existing fisheye optical system suitable for 360° no-dead angle security monitoring and unmanned driving fields generally has the defects of large number of lenses, complex structure, and aspheric design. Contents of the invention [0003] In order to solve the problems existing in the prior art, the present invention provides an ultra-wide-angle spherical fish-eye optical system, which overcomes the problems of the existing fish-eye optical system with a large number of lenses, a complex structure, and an aspheric design. [0004] The technical solution adopted by the present invention to solve technical problems is as follows: [0005] The super wide-angle spherical fisheye optical system is provided in sequence along the optical axis from the object plane to the image plane: the first lens...
