ABSTRACT:
A microstructured antireflective texture is disclosed comprised of an engineered array of protuberances arranged on a non-periodic lattice. The average distance between said protuberances is in the subwavelength regime of the waveband for which the antireflective effect is desired. The non-periodic arrangement of protuberances acts to suppress blue-green backscattered light that is commonly seen diffracting from antireflective textures that use strictly periodic lattice arrangements. Embodiments of the invention include the randomized square pattern, and the quasicrystal pattern.
