Abstract

Large format deformable mirrors have been proposed in the last few years as key elements to implement active wave front correction for future space telescopes. Active optics is, in fact, an enabling technology for high stability, high contrast and high resolution systems. We present in this work a 40 cm diameter prototype, together with its laboratory characterization, based on voice-coil actuators. When the mirror is operated, such contact-less actuation allows the optical surface to float at a given distance from its support and the mirror is virtually decoupled from the mechanics; such condition offers an intrinsic isolation from external vibrations with no need for further damping devices. We demonstrated experimentally this concept in the laboratory on a dedicated interferometric setup, registering a substantial rejection of the vibrations injected. We will present in this work the test results and a roadmap for future developments.
