Aerotech: High-performance galvo scanner control

The Nmark GCL controls Aerotech’s AGV series scanners resulting in industry-leading settling times, 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.

Full servo state control with "zero-tracking error" eliminates speed-related part distortion such as necking on circles and rounding of corners. Position-based laser firing (PSO) with windowing maintains consistent spot spacing over a wide range of operating speeds.
