Abstract

MORFEO (Multi-conjugate adaptive Optics Relay For ELT Observations), formerly known as MAORY, is the Multi-Conjugated Adaptive Optics (MCAO) module for the Extremely Large Telescope (ELT). MORFEO is designed to feed the near-infrared camera MICADO (with the capability to feed a second port dedicated to a future instrument) with both MCAO and Single-Conjugated AO (SCAO) operation modes. The optical configuration provides a one-to-one imaging of the telescope focal surface on the two ports and it is equipped with two post-focal deformable mirrors together with the 6 Laser Guide Star (LGS) and 3 Natural Guide Star (NGS) channels for wavefront sensing and tomographic reconstruction. We present here the Final Design of the MORFEO optical configuration and the expected performances.
