Abstract
A lens module comprises a lens barrel, a first lens, a first shading chip and a second lens, the first lens, the first shading chip and the second lens are assembled in the lens barrel sequentially from the object side to the image side, the first lens comprises a first optical portion and first non-optical portions surrounding the first optical portion, and each first non-optical portion comprises a first assembly surface and a second assembly surface, wherein the first assembly surface is close to the object side while the second assembly surface is back to the first assembly surface. The second lens comprises a second optical portion and second non-optical portions surrounding the second optical portion, and each second non-optical portion comprises a third assembly surface close to the object side. The first shading chip is separately arranged among the second assembly surfaces and the third assembly surfaces, and orthographic projection of the first non-optical portions on the first shading chip along the optical axis direction completely falls into the first shading chip. Light projected to the first non-optical portions is completely blocked by the first shading chip so as not to be projected to the second non-optical portions, and generates multiple times of reflection on the second non-optical portions, so that reflected light grains in imaged images are reduced.
