Title:
ONBOARD CAMERA LENS
Document Type and Number:
WIPO Patent Application WO/2019/242411
Kind Code:
A1
Abstract:
An onboard camera lens comprising, in order from an object side to an image side: a first lens having a negative optical power, wherein an object-side surface thereof is a convex surface and an image-side surface thereof is a concave surface; a second lens having a negative optical power, wherein an object-side surface thereof is a concave surface and an image-side surface thereof is a convex surface; a third lens having a positive optical power and both surfaces thereof being convex surfaces; a diaphragm; a fourth lens having a positive optical power and both surfaces thereof being convex surfaces; a fifth lens having a negative optical power and an object-side surface thereof being a concave surface, wherein the fourth lens and the fifth lens are combined into a cemented lens; a sixth lens having a positive optical power, and an object-side surface thereof being a convex surface; an optical filter; wherein the second lens, the third lens, the fourth lens, and the fifth lens are glass spherical lenses, and the first lens and the sixth lenses are glass aspherical lenses. The onboard camera lens significantly increases the distortion of a lens in the range of a narrow field angle to satisfy special algorithm requirements of an onboard system, and improves the resolving power of the lens module while effectively controlling the aperture and length of the lens.
