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.
