Galvo Scanner Control
Aerotech's Nmark GCL features such as full state feed-forward, 200 kHz servo rates, and look-ahead-based velocity control.
Aerotech’s Nmark GCL controls AGV series scanners resulting in long-term thermal stability, and micron-level tracking accuracy due to advanced features such as full state feed-forward, 200 kHz servo rates, and look-ahead-based velocity control. The Nmark GCL uses advanced interpolation electronics to provide up to 26-bits of effective resolution. Onboard real-time 2D calibration ensures accurate beam placement over the entire field of view. Scanner-based processes can now be programmed in the same fashion as traditional X/Y stage-based applications by using the Position Synchronized Output functionality. An Infinite Field of View (IFOV) combines scanner and servo motion to expand the scanner working area. The full servo state control with “zero-tracking error” eliminates speed-related part distortion such as necking on circles and rounding of corners.
