WebTraditional optical glasses (e.g., BK7, fused silica) are not considered good materials for cutting optical surfaces with single point diamond tools. The cutting mechanics result in a deep layer of subsurface damage that must be removed by polishing. The polishing renders the process too expensive for practical use. WebFor example, natural quartz glass in the UVC range has a much lower light transmission than optical quartz glass (fused silica). If high transmission of more than 80 % at 185 nanometers is required , fused quartz cannot achieve this . Besides, the optical homogeneity of natural fused quartz is generally much worse than that of optical grade ...
