Abstract

There is a need for precisely figured large sapphire windows with dimensions of up to 20 inches with thicknesses of 0.25 inches that will operate in the 1- to 5-micron wavelength range. In an effort to reduce manufacturing cost during grinding and polishing, OptiPro Systems is developing technologies that provide an optimized deterministic approach to making them. This development work is focusing on two main areas of research. The first is optimizing existing technologies, like deterministic microgrinding and UltraForm Finishing (UFF), for shaping operations and precision controlled sub-aperture polishing. The second area of research consists of a new large aperture deterministic polishing process currently being developed at OptiPro called UltraSmooth Finishing (USF). The USF process utilizes deterministic control with a large aperture polishing tool. This presentation will discuss the challenges associated with manufacturing large sapphire windows and present results on the work that is being performed to minimize manufacturing costs associated with them.
