High-pixel ultra-wide-angle optical system and its applied lens

Abstract

The embodiment of the invention discloses a high-pixel ultrawide-angle optical system which at least comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens which are arranged from an object plane to an image plane in turn along an optical axis. The object plane side of the first lens is a convex plane, the image plane side is a concave plane, and the focal power is negative; the object plane side of the second lens is a convex plane, the image plane side is a concave plane, and the focal power is negative; the object plane side of the third lens is a convex plane, the image plane side is a concave plane, and the focal power is positive; the object plane side of the fourth lens is a convex plane, the image plane side is a convex plane, and the focal power is positive; the object plane side of the fifth lens is a concave plane, the image plane side is a convex plane, and the focal power is negative; and the object plane side of the sixth lens is a convex plane, the image plane side is a convex plane, and the focal power is positive. Besides, the embodiment of the invention also discloses a camera lens. The high-pixel ultrawide-angle optical system is mainly composed of six lenses so that the number of the lenses is less and the structure is simple, and thus the high-pixel ultrawide-angle optical system has great properties of large aperture, large visual angle, high pixel and great athermalization.

Description

Technical field: [0001] The invention relates to an optical system and its applied lens, in particular to a high-pixel ultra-wide-angle optical system and its applied lens. Background technique: [0002] With the application of panoramic lens camera technology and the development and utilization of panoramic parking systems, a series of ultra-wide-angle lens products have appeared on the market: for example, the patent application with publication number CN103293640A mentions a fisheye optical lens, but the lens uses 11 The lens has the defects of a large number of lenses and a complex structure. Invention content: [0003] In order to overcome the problems of a large number of lenses and a complex structure in existing optical systems or lenses, an embodiment of the present invention provides a high-pixel ultra-wide-angle optical system on the one hand. [0004] A high-pixel ultra-wide-angle optical system, which sequentially includes at least a first lens, a second lens...
