19 Fibre Only Option: High Definition Mode (HDM) HDM focal plate Assumptions 12 science channels Light transfer optics: - Pick off mirror - Intermediate fold mirror - Receiving mirror In-plane rotation >180deg Courtesy: David Pearson Known issues Further degrees of freedom required in each optical item. Pick-and-place system required to cope with optical items of different shapes and sizes. Synchronisation of plate rotation with LGS system. Spectrographs See Poster by Jagourel et al.

20 Fibre Only Option: High Multiplex Mode HMM focal plate Courtesy: David Pearson Assumptions 120 science channels Buttons with fibre retraction scheme Stepped focal plate In-plane rotation >180deg Known issues Change in field curvature causes difficulty in fibre alignment and focus. Synchronisation of plate rotation with LGS system. Spectrographs See Poster by Jagourel et al.
