Abstract

The general term for optical surfaces better than the lowest level of the scratch-dig standards has become "supersmooth", and is seen in technical literature as well as in advertising pieces. A performance number, such as BRDF, which can be measured from the uncoated optical surface by equipment such as the Variable Angle Scatterometer at the Air Force Wright Aeronautical Laborataories at Wright-Patterson Air Force Base is proposed as a method of generating better optical surface specifications. Data show that surfaces of average BRDF values near 10 parts per billion per steradian (0.010 PPM/Sr) for β-β_o = 0.5, are now possible and measurable.
