Galvanometers & Galvo Controllers

Liberty International offers new Nmark AGV Galvanometers and Nmark CLS Galvo Controllers from Aerotech that 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 exclusive Infinite Field of View feature seamlessly synchronises servo and scanner motion to allow fast positioning over the entire servo travel, eliminating galvo field of view constraints. The Position Synchronized 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 advanced 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. Aerotech is a leading global supplier of positioning and motion control products for industry, government, science and research institutions. Its products provide critical performance for demanding applications requiring high precision, high-throughput motion control solutions. The company also offers Direct-Drive Rotary Stage with Large Aperture, Linear Motor Nanopositioner, Two Axis, Rotary Air-Bearing Stages.
