One reviewer suggested that it would have been of interest to scan the surfaces in three dimensions by using an optical profiler to show the surface finish over a macroscopic region. This was not done for two reasons. First, the surfaces appeared isotropic when profiles of 1 to 2 mm were taken for different sample orientations on the China Lake Talystep; no additional structure other than the usual longer surface spatial wavelength waviness was seen. Second, optical profilers do not have as good lateral resolution as mechanical profilers when the latter are used with a sharp stylus and light loading. Therefore more fine structure could be seen in the profiles made with the mechanical profiler. The intent of the study was to look at the surface microstructure by using the profilers and to measure the overall figure (flatness) with the CSIRO interferometer.
The abrasives used in this study and their suppliers are as follows: cerium oxide in the form of Liquid 85 and Vitrox R were obtained from Universal Photonics, 495 West John Street, Hicksville, N.Y. 11801; cerium oxide in the form of Microgrit was obtained from Micro Abrasives Corporation, 720 Southampton Road, P.O. Box 669, Westfield, Mass. 01086; aluminum oxide in the form of Ultra-Sol 200A and Special Ultra-Sol (not a commercial product but can be specially ordered) were obtained from Solution Technology, Inc., P.O. Box 2508, Matthews, N.C. 28106; colloidal silica in the form of Nalcoag 2350 was obtained from Rodel Products Company, 9495 East San Salvador Drive, Scotsdale, Ariz. 85258; colloidal silica in the form of Syton can be obtained from many different suppliers world wide; titanium dioxide in the form of Anatase E was obtained many years ago in Australia, but it is no longer made there.
