Potential NASA Commercial Applications: The Phase I program was structured to primarily support a critical need of NASA AMTD-2. Specifically, developing a process that can safely and economically perform mirror backside light weighting of very large telescopes. The Phase II project will result in a technology that will be immediately available to support broad a range of NASA space and ground based optics programs. The Phase II workscope is structured to support the 1/3 scale AMTD-2 mirror fabrication and scale up efforts, so the results of this SBIR will very likely be applied under ongoing and future NASA projects. Raytheon has stated in a letter of support that the Ormond milling technology is a critical technology to reduce machining and fabrication times, as well as risk in processing of ceramic and glass ceramic substrates. They state that the process has potential applicability to several NASA programs including JDEM, IXO, LISA, ICESAT, ATLAST, CLARREO, ACE. Trex has stated that this technology is critical to manufacturing the difficult to machine SiC optics materials that are produced there.
