One of the factors influencing the focus size in diffractive-refractive optics is the quality of diffracting surface. If the surface is uneven, then the diffraction at each point of the surface is a combination of an asymmetric and inclined diffraction. This some what deviates and spreads the diffracted beam. It is shown that in some cases the etched surface may create the spread of the diffracted beam,such that it causes a significant broadening in the focus.
