Galvo scanner control for accurate tracking
Aerotech’s Nmark galvo scanner control is designed to provide strong settling times, long-term thermal stability, and micron-level tracking accuracy. Features include 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 2-D calibration is designed to ensure accurate beam placement over the entire field of view. The ability to accurately place a laser spot as a function of X/Y axis position is a key feature of Aerotech’s linear positioning stages for laser processing applications, and with the release of the Nmark GCL, this functionality is now available for scanner applications. The ability to accurately trigger the laser as a function of position removes the need to program mark, jump, and polygon delays, which in turn reduces programming complexity. 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.
