Intelligent domestic high-pixel wide-angle lens

Abstract

The invention discloses an intelligent domestic high-pixel wide-angle lens, which comprises an optical filter, a first lens system and a second lens system. The first lens system is composed of a first lens and a second lens; the first lens is a meniscus lens with negative power and its convex surface facing towards an object surface; the second lens is a double convex lens with positive power; the second lens system is composed of a third lens, a fourth lens and a fifth lens; the third lens is a double convex lens with positive power; the fourth lens and the fifth lens are bonding lenses which are bonded with each other; the first lens, the second lens, the third lens, the fourth lens and the fifth lens are coaxially arranged between the object surface and an image surface in sequence; the optical filter is arranged between the fifth lens and the image surface. According to the intelligent domestic high-pixel wide-angle lens, by means of the five spherical glass optical lenses, the angle of diagonal photographing can reach up to 160 degrees at most, the intelligent domestic high-pixel wide-angle lens has the advantages of being big in field angle and high in resolution, shooting dead corners are reduced to the greatest extent under the condition that image brightness is guaranteed, and the high-pixel wide-angle lens is suitable for intelligent domestic usage.

Description

technical field [0001] The invention relates to a wide-angle lens, in particular to a high-pixel wide-angle lens for smart home, and belongs to the technical field of optical imaging.
