The structure of a surface layer of ground glass consists of relief layer and crack layer. Their dimensional characteristics influence directly the subsequent polishing process. The understanding of the role of both layers in the polishing process is the key factor for optimizing the efficiency of optical surfacing by selecting proper techniques for both grinding and polishing operation. In this paper, the role of the microstructure of the grind surface layer in polishing process will be discussed; methods of its evaluation presented, and several examples of surface structure for some representative grinding methods evaluated.
