Abstract
Working with our System Integrator partner (ITT-Exelis) and Richard Lyon (NASA/GSFC Principal Investigator Compact Achromatic Visible Nulling Coronagraph Technology Maturation) and his telescope expert Lee Feinberg, Trex will perform a preliminary design of a 1-meter aperture, ultrastable, UVOIR telescope made using Trex Chemical Vapor Composite Silicon Carbide (CVC SiC?). The highly athermal silicon carbide telescope provides an affordable solution for the Balloon Exoplanet Nulling Interferometer (BENI) Mission to qualify the VNC, with traceability to the requirements of the ATLAST observatory.Trex also proposes to demonstrate replicated, powered CVC SiC?substrates using a new, polishable graphite mandrel material which allows the release of our CVC SiC?deposit from the mandrel with a spectral finish. The new process eliminates rough and fine grinding of the optical surface, which is directly ready for fine lapping and polishing. The payoff will be at least a factor of 2X reduction in the areal cost of high performance CVC SiC?mirrors, with an associated reduction in schedule on the order of 6-months. Using meniscus mirror designs for lightweighted mirrors in the telescope, rather than a web-based isogrid design, will also reduce the cost and schedule for CVC SiC?mirrors, while not sacrificing weight or stiffness.
