Conceptual design for the optomechanical systems of the New Robotic Telescope

The New Robotic Telescope (NRT) will be the largest fully robotic telescope in the world (4-m class). The primary mirror (M1) will be comprised of 18 independent 960 mm hexagonal segments with an actively controlled position to maintain the shape of the optical surface. The secondary mirror (M2) will be a lightweighted circular mirror of 1270 mm of diameter. This contribution presents the conceptual design and preliminary results of the M1 segment support assembly and a first study of two lightweighted substrate candidates for the M2 mirror.
