Aerotech Nmark AGV galvanometers and CLS galvo controllers for laser micromachining

Nmark AGV galvanometers and Nmark CLS galvo controllers from Aerotech are claimed to provide increased throughput with industry-leading resolution for laser micromachining applications.

Using advanced interpolation electronics, the Nmark controller provides greater than 24 bits of effective resolution with 2D positioning accuracy of 10 microns or better.

An Infinite Field of View feature seamlessly synchronises servo and scanner motion to allow fast positioning over the entire servo travel, eliminating galvanometer field-of-view constraints.

The position-synchronised output feature of the controller ties laser pulses directly to galvo position, allowing accurate triggering of the laser without delays to compensate for the response time of the scanner mirror motion. This improves part quality and reduces programming complexity.

Applications that can benefit from these capabilities include placing a series of parallel lines that require consistent line to line spacing and accommodating patterns with small radii that must be traversed at high speeds while maintaining tight dimensional tolerances.

The AGV Galvo Scanners are available with 10, 14 and 20 mm apertures and F-Theta lens interface for maximum flexibility. Many choices of mirror surface treatments accommodate a variety of laser wavelengths.
