A mathematical model relating the measured parameters of the Technology Mirror Assembly (TMA) to its final performance is developed. This scalar scattering model is valid for large and small amplitude features. It allows the user to specify power spectral densities and/or autocovariance functions within any spatial bandwidth, including microroughness. New TMA data in the bandwidth of about 0.1-1000/mm are presented, predicting performance, and results are compared with X-ray test data. Assembly, alignment, and particulate contamination are also accounted for. Finally, improved performance expected after repolishng is commented on.
