For a Binary 2 surface do you use 100 for the normalization radius (units in mm) in the extra data editor?
100 mm is the default normalization radius, however this value is not intended to be used for all designs. The normalization radius can be set to any convenient value as long as it is provided with the prescription for the phase coefficients. The phase across the surface is defined as a function of the normalized radius, rho. If you change the normalization radius, you would simply have to re-optimize the phase coefficients to get the same phase across the surface. The normalization is frequently set equal to the semi-diameter of the surface, or to a value of 1.0. If set equal to the semi-diameter, the sum of the phase coefficients on all terms will conveniently give the total phase at the edge of the part, where all the powers of rho in the phase equation are equal to 1.0. If the normalization radius is set equal to 1.0, rho will scale with lens units, which may also be convenient for calculating the phase as function of surface coordinates.
