Claim Text:
1. An optical surface extending in at least two Cartesian base dimensions (X, Y), wherein a cross-section of the optical surface taken in either of said two Cartesian base dimensions (X, Y) comprises a first plurality of protuberances extending to the same direction in a third Cartesian dimension (Z), wherein said cross-section of the optical surface comprises a second plurality of protuberances extending to the opposite direction as the first plurality of protuberances in the third Cartesian dimension (Z), the pluralities of protuberances form converging and diverging optical shapes for mixing different wavelengths scattering from the optical surface, and each protuberance is separated by a section along a base surface defined by said two Cartesian base dimensions (X, Y).
