The Nmark GCL high-performance galvo scanner control from Aerotech Inc. is a closed-loop, two-axis servo drive for the AGV series of scanners.
The scanner control provides leading settling times, long-term thermal stability and μm-level tracking accuracy due to 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.
The device provides users of scanner applications with the ability to accurately place a laser spot as a function of XY axis position.
