Future UV/Optical telescopes will require increasingly large apertures to answer the questions raised by HST, JWST, Planck and Herschel, and to complement the 30-m ground-based telescopes that will be coming on line in the next decade. Large aperture telescopes are required to provide the spatial resolution and sensitivity needed to perform frontier measurements of the future. These include stellar photometry and archaeology of distant galaxies, ultraviolet spectroscopy of the cosmic web, and high resolution imaging that will probe the formation and structure of the first galaxies, the properties of dark matter, and the evolutionary phases of pre-planetary systems. Low-cost, lightweight optics are required to enable the development of such large aperture UV / Optical telescopes in the 2020 decade. Technologies are therefore required that provide a high degree of thermal and dynamic stability, and wave front sensing and control, while minimizing the factors which drive the cost of flagship missions -- complexity, testing challenges, and mass.
