Single- and Dual-Axis Scanning Galvo Systems for Large Beam Diameters
Notes
c The unit can operate beyond these limits with reduced performance until protections
trigger (250 Hz <10 sec). For a safe operation stay below 50 Hz 20Vpp sinewave
d Using heat sink to keep temp <35°C (see Section 3.1.2.).
e The settling time for the mirror to stop moving once the drive signal is removed.
