AEROTECH Automation1 GL4 Galvo Laser Scan Head Linear Drive



Automation1 GL4 Galvo Laser Scan Head Linear Drive
The Automation1 GL4 is a high-performance, closed loop 2-axis linear servo drive for controlling our AGV laser scan heads. With an effective scanning resolution of greater than 24-bit and advanced features like Infinite Field of View (IFOV), Position Synchronized Output (PSO) and Enhanced Scanner Control (ESC), the GL4 stands out as a superior scan head drive solution for your most demanding high-precision applications.
Design Features
100 kHz trajectory rate & 200 kHz servo rate eliminate speed-related part distortion such as necking on circles & rounding of corners
Effective scanning resolution of >24 bit provides industry-leading resolution resulting in micron scale accuracy & repeatability for Aerotech AGV scanner products
On-board real-time 2D calibration for both planar distortion & power correction enable accurate laser positioning & uniform power distribution
External clock input for synchronization with mode-locked lasers
Infinite Field of View (IFOV) combines standard linear & rotary motion to produce scanner trajectories with single-digit micron accuracy over most work area sizes
PSO allows for commanded laser pulses at up to 12.5 MHZ & latencies as low as 80 nanoseconds, enabling real spatial domain pulse control
Optional Enhanced Scanner Control (ESC) is a real-time trajectory optimization tool that dramatically improves tracking error for all motion types
Automation1
Powered by Automation1, the GL4 is more than a scan head drive – it’s a fully featured, real-time PC-based automation controller that can accommodate up to 32 servo axes or five scanners. Coordinate up to 64 active, simultaneous tasks and control an entire machine programmed with AeroScript™ – or use the .NET, C and Python APIs to create your own HMI. The low-latency hyperwire network allows all axes to perform low-latency motion, enabling complex kinematics such as 5-axis contouring with laser scan heads and servo axes – something no other scanner control solution on the market can do
