This session will be on the fabrication science and technology of optical components with focus on, but not limited to, lasers and telescope applications. The field of optical fabrication, which transforms bulk glasses or ceramics via grinding, cutting, polishing, etching, molding, and additive manufacturing into precision optics, continues its migration from more of an art to a science. Included in this scope will be a multidisciplinary (physics, chemistry, fracture mechanics, mechanics, tribology) approach to understanding the complex interactions between the glass or ceramic workpiece, abrasive or polishing media, and the tool, which influence the final workpiece properties (surface quality, surface roughness, and surface figure). In addition, this scope will include novel and recently developed finishing technologies, techniques, and characterization methods.
