Developing faster more efficient processing methods for the fabrication of large sapphire windows has the potential to reduce their overall cost. The hardness of the material as well as its crystallographic orientation results in low material removal rates that lead to processing times longer than desired. These low removal rates are present in both the grinding and polishing phases of the process and are one of the primary cost drivers. By increasing the material removal rate during fabrication without distorting the optical wavefront, substantial cost savings can be achieved. OptiPro Systems has the unique opportunity to develop a deterministic mid-aperture sized polishing (USF) UltraSmooth Finishing process. This process will have the ability to remove material at a rapid rate, and use metrology data as input for controlling the wavefront of the sapphire window. OptiPro"s technologically advanced optical manufacturing capabilities along with a support partnership with Ted Turnquist from Meller Optics, an expert in sapphire processing, gives us a very strong team, and a clear path towards solving the difficult problems associated with reducing the grinding and finishing costs associated with manufacturing sapphire windows.
