Ultra-wide-angle ultra-high-pixel optical system

Abstract

The embodiment of the invention discloses an ultra-wide-angle ultra-high-pixel optical system. The ultra-wide-angle ultra-high-pixel optical system sequentially comprises 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 and a tenth lens from an object plane to an image plane along an optical axis; the object plane side of the first lens is a convex surface, the image plane side is a concave surface, and the focal power is negative; the second lens, the fourth lens and the eighth lens are biconcave lenses, and thefocal power is negative; the third lens, the fifth lens, the sixth lens and the seventh lens are biconvex lenses, and the focal power of the lenses is positive; the focal power of the ninth lens is positive; and the focal power of the tenth lens is negative. According to the embodiment of the invention, the ultra-wide-angle ultra-high-pixel optical system mainly comprises 10 lenses, and is reasonable in the number of lenses, ingenious in structure, small in size and reasonable in cost; different lenses are combined with each other and the focal power is reasonably distributed, so that the ultra-wide-angle ultra-high-pixel optical system has an ultra-wide angle, 48 million ultra-high pixels, a large target surface and other good performance.

Description

Technical field: [0001] The invention relates to an optical system, in particular to an ultra-wide-angle and ultra-high-pixel optical system suitable for fields such as sports cameras and drones. Background technique: [0002] With the increasing application of high-resolution technology, especially the wide application of ultra-wide-angle lenses, a series of high-pixel lens products have appeared on the market. However, its optical system has the defects of complex structure, large volume, not high enough pixels, and small target surface. Invention content: [0003] In order to overcome the problems of complex structure and large volume in existing optical systems, an embodiment of the present invention provides an ultra-wide-angle and ultra-high-pixel optical system. [0004] The ultra-wide-angle ultra-high-pixel optical system includes: the first lens, the second lens, the third lens, the fourth lens, the fifth lens, the sixth lens, the seventh lens, and the eighth len...
