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.
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.
- Closed-loop, two-axis servo drive for Aerotech’s AGV series scanners
- Infinite Field of View (IFOV) seamlessly combines scanner and servo motion to expand the scanner working area
- 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
- ?External clock input for synchronization with mode-locked lasers
