3D printing for astronomical mirrors
Melanie Roulet, Carolyn Atkins, Emmanuel Hugot +3
3D printing, also called additive manufacturing, offers a new vision for optical fabrication in term of achievable optical quality and reduction of weight and cost. In this paper w…
Superpolished OAPs for WFIRST CGI
Melanie Roulet, Emmanuel Hugot, Carolyn Atkins +3
Exoplanet imaging requires super polished off-axis parabolas (OAP) with the utmost surface quality. In this paper we describe an innovative manufacturing process combining 3D print…
Space Project for Astrophysical and Cosmological Exploration (SPACE), an ESA stand-alone mission and a possible contribution to the Origins Space Telescope
Denis Burgarella, Andrew Bunker, Rychard Bouwens +30
We propose a new mission called Space Project for Astrophysical and Cosmological Exploration (SPACE) as part on the ESA long term planning Voyage 2050 programme. SPACE will study g…
CASTLE: performances and science cases
S. Lombardo, F. Prada, E. Hugot +23
We present here the Calar Alto Schmidt-Lemaitre Telescope (CASTLE) concept, a technology demonstrator for curved detectors, that will be installed at the Calar Alto Observatory (Sp…
Stress mirror polishing for future large lightweight mirrors: design using shape optimization
Sabri Lemared, Marc Ferrari, Christian Du Jeu +3
This study proposes a new way to manufacture large lightweight aspherics for space telescopes using Stress Mirror Polishing (SMP). This technique is well known to allow reaching hi…
