Abstract

Most optical components consist of surfaces which must be manufactured via the cold working of glass: Rough grinding, microgrinding (lapping under fixed nominal pressure, or deterministic microgrinding under fixed infeed rate), and polishing [Izumitani, 1986; Karow, 1993]. The quality of the resulting optical surface may be described by its surface roughness, subsurface damage, or the residual stresses arising in the manufacturing process. The quality of the surface is determined by process parameters (pressure or infeed rate, relative speed, coolant, abrasive size and shape, etc.) and by glass chemo-mechanical properties. An optics manufacturing map will consist of a predictive scheme whereby the process parameters and the glass material properties can be used to predict the quality of the resulting optical surface.
