Abstract
Optical designers have used the aspheric expansion given in equation 1) for many years. z= CQ2 + 44 + eQ6 + fQ8 + g Q10 1) 1 +0 â€" (k + 1)C2Q2 This surface is rotationally symmetric about the optical axis which runs along the z direction in cylindrical coordinates. The surface sagitta, "sag", is given by z and i)=N/xa + ya is the radial distance from the optical axis.
