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…
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…
