Abstract

A Scanning Auger Microprobe was used to examine the surfaces of diamond turned electroplated mirrors and conventionally prepared mirrors. The change in contamination was noted in each, following an ion polishing process and a vacuum annealing process. Carbon and oxygen are the most predominant surface contaminants and are present in the top 12-25A. The depth of contamination was determined by Argon sputter etching the surfaces. Much of the contamination is due just to air. Also discussed are Auger analysis performed in conjunction with our multilayer dielectric enhancement study of 10.6 micron optics. KEY WORDS: Auger spectroscopy, diamond turned mirrors, surface physics, contaminants, dielectric coatings.
