(Opto)mechanical design of the Single Laser Adaptive Optics system for ELT/METIS

The Mid-infrared ELT Imager and Spectrograph (METIS), which will be one of the first-light instruments on the Extremely Large Telescope (ELT), will be equipped with an Adaptive Optics (AO) system that will use a natural guide star as reference for the correction of the wavefront errors, introduced by the atmospheric turbulence. Even though this...
