Abstract
The Optical Relay Module of the MOSAIC multiple-object spectrograph is used to relay 400-1800nm light picked off from the ELT focal plane to either a fibre-based integral field unit or a natural guide star wavefront sensor. Here we present the preliminary optical design offering a telecentric exit beam with a focal-ratio of F/17.718 and the opto-mechanical analysis of flexures with a study of the impact in the optical layout performances such as: deviation of the PSF centroid, tip-tilt of the image focal plane, variations of the wavefront error, optical quality and pupil wandering at the deformable mirror position.
