Abstract
Since modern methods of surface examination show no surface to be perfect it becomes necessary to agree damage thresholds acceptable for particular applications. Recent tests have shown, as presented here, that the severity of different scratches can be compared by measuring the proportion of incident light they remove from a beam.
