High-Performance Galvo Scanner Control

The Nmark GCL from Aerotech 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.
