Paper Abstract

Instrumental techniques available for measuring the roughness of optical surfaces include mechanical profilometers and optical heterodyne profilometers, both of which yield surface profiles, and total integrated and angle-resolved scattering, from which roughness values can be derived using appropriate theoretical relations. These methods are used to measure the roughness of a set of roughness standards made by polishing ground Zerodur surfaces for progressively longer times. The measured roughnesses are compared, and the reasons for the differences are discussed.
