Key M2 Positioner Requirements Motion Requirements DOF Piston Tip & Tilt X & Y De-center Range of Motion +/- 15mm +/- 2 mrad +/- 15mm Max. Error ±2 μm ± 30 arcsec ± 100 μm Accuracy: 30mm RMS Smoothness of motion is critical (TBD) Control Bandwidth: > 0.1 Hz <strong>TMT</strong>.OPT.PRE.09.099.DRF03 34
M3 Tracking Motion M3 must be able to steer the beam to any one of ~ 8 science instruments on the Nasmyth platforms For instruments not on the elevation axis, the M3 must track at variable rates in tilt and rotation as the telescope moves in elevation Tip/Tilt range: 50°+/- 8° Rotation range: +/-180° Elevation Axis MIRES <strong>TMT</strong>.OPT.PRE.09.099.DRF03 35
