  • Patent number: 11681078
    Abstract: The present disclosure provides a structure having a low reflectance surface, wherein the structure comprises: a base plate; and a plurality of inclined rods protruding from a first face of the base plate and inclined relative to a normal line to the first face, wherein the inclined rods are spaced from each other. Travel paths of light beams in the structure may be longer along the inclined rods. As a result, a larger amount of light may be absorbed by the structure having a low reflectance surface. The amount of light-beams as reflected from the structure having a low reflectance surface may be significantly reduced.
