Maximum wavefront error = 1 / 12.2 wave at zone 4

Polish excellent, surface smoothness very good, diffraction edge excellent.
Very good figure of revolution (no detectable astigmatism).

Results for individual sets of readings:
	Reading set 1: 1 / 13.8 lamda, Max Trans Abberation=0.87
	Reading set 2: 1 / 10.2 lamda, Max Trans Abberation=1.29
