Final assembly of the ULTRA 1-m carbon fiber optical telescope

Presented is a poster presentation relating to the final assembly and testing of the Ultra Lightweight Telescope for Research in Astronomy, ULTRA [1]. The program is a 3-year Major Research Instrumentation (MRI) program funded by NSF. Objectives are to demonstrate carbon fiber reinforced plastic (CFRP) composite mirrors for ground-based optical telescopes. Presented will be final assembly of the telescope including the unique features of the system including the 27 kg primary mirror, hexapod secondary mirror control, motorized iris for the primary mirror cover. Also presented are results of the optical testing of the 0.4m mirrors used as developmental optics in the program.
