Paper Abstract

Presented is a lightweight mirror compatible with the extremely large telescopes being proposed. The mirror exhibits an areal density of less than 12 kg/m2, which is the same relative areal density as the primary mirrors on the 100-meter Robert Byrd Radio Telescope. The panels can be fabricated in 2.5-meters diameter with traceability to 4-meters. Presented are preliminary results of a set of large demonstrator mirrors, their characteristics and traceability to producing 4-meter low-cost and easily fabricated mirror segments for large telescopes.
