Problems solved by technology
[0003] The current lens uses the light hole of the lens barrel as the diaphragm, but when the lens barrel is formed, because the sharp corner is thin, the molding is not full and shiny, so when the light hits the lens, it will be reflected to the image. Harmful light spots are formed on the surface, which affects the molding quality

The invention discloses a lens and electronic equipment. The lens comprises a lens barrel, multiple lenses and a first shading piece, wherein the end, which is close to an object side, of the lens barrel is an object side end, and the object side end is provided with a first through hole; the multiple lenses are arranged in the lens barrel, each lens comprises an optical effective area and a bearing area, the bearing area surrounds the optical effective area, and the lens, which is close to the object side end, in the multiple lenses is a first lens; and the first shading piece is provided with a second through hole, the first shading piece is arranged between the object side end and the first lens, the first shading piece covers the bearing area, and in a plane perpendicular to the optical axis, the projection of the first shading piece on the plane covers the projection of the object side end on the plane. Therefore, by adding the first shading piece between the lens barrel and the first lens, the effect of eliminating stray light can be achieved, and the forming difficulty of the light through hole of the lens barrel can be reduced.
Description
technical field [0001] The invention relates to the field of lens technology, in particular to a lens and electronic equipment. Background technique [0002] In recent years, customers have become more and more demanding on mobile phone cameras, especially for stray light. [0003] The current lens uses the light hole of the lens barrel as the diaphragm, but when the lens barrel is formed, because the sharp corner is thin, the molding is not full and shiny, so when the light hits the lens, it will be reflected to the image. Harmful spots are formed on the surface, which affects the molding quality. Contents of the invention [0004] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, an object of the present invention is to provide a lens, which can achieve the effect of eliminating stray light and improve the quality of the lens. [0005] The present invention further provides an electronic device. [0006] ...
