Description

1. ELT (Extremely Large Telescope) is the world’s largest telescope (39m diameter) under construction by ESO (https://elt.eso.org/) at Cerro Armazones in Chile. ELT is considered worldwide to be one of the highest priorities in ground based astronomy. MORFEO (http://wwwmaory.oabo.inaf.it/), as a first generation ELT instrument, will help compensate for the distortion of light caused by turbulence in the Earth’s atmosphere. MORFEO is a Multi-Conjugate Adaptive Optics (MCAO) module that will allow spatially uniform adaptive optics compensation over a large field of view (about 1 arcmin2) with high sky coverage. Wavefront sensing is performed by six Laser Guide Stars (LGS) and three Natural Guide Stars (NGS), for the measurement of high and low-order wavefront perturbations respectively. Finally, the wavefront error compensation is performed by two adaptive post focal Deformable Mirrors (DMs) located inside MORFEO (the core of the instrument), which work together with the telescope’s adaptive and tip-tilt mirrors M4 and M5 respectively. The overall optical path will consist of several 1m class optical elements: 6 flat folding mirrors, one corrective plate, two aspherical mirrors…
