Abstract

MORFEO (Multi-conjugate adaptive Optics Relay For ELT Observations), formerly known as MAORY, will play a crucial role in deploy a corrected Field of View to ELT instruments. To allow the wavefront sensing, a Laser Guide Stars (LGS) channel is foreseen composed by two subsystems: an objective to materialize a monochromatic (sodium layer wavelength) focal plane (the LGS Objective, LGSO) and the proper LGS wavefront sensor system (LGSWFS). Here we report about the LGSO optical design, reviewing the requirements, summarizing the geometrical and optical properties of LGSO elements and discussing the expected performances, both for the nominal system and tacking into account tolerances.
