: Diamond turning copper and other metals, to produce mirror surfaces with reflectivities generally higher than can be obtained by lapping and polishing, has become an important new technology. Evaluation of the finish of these surfaces requires careful examination, using optical instruments. This document provides background information about the theory and equipment involved in this program. Data from several specimens have been acquired that show the type of surface finish that is obtained. Mirrors have been fabricated that show the state of the art that has been achieved in diamond turning copper and nickel.
