Paper Abstract

ECM investigated in the past three years the repeatability and reproducibility of Cesic® for a serial production of optical applications. Under ESO - European Southern Observatory - contract ECM performed also a feasibility study for the manufacturing of Cesic® primary and secondary mirror segments for the Overwhelmingly Large (OWL) Telescope. The main issues of this study were (1) to develop a new manufacturing process suitable for the serial production of the OWL Cesic® mirror segments (~2550), including the polishable surface (but not the polishing itself), that greatly reduces cost and schedule compared to traditional manufacturing; and (2) to design a manufacturing facility that optimises the new manufacturing process.
