Galvo and Controller Combination Offers Infinite Field of View and 24-Bit Resolution

Advanced Features

The ability to accurately place a laser spot as a function of X/Y axis position is a key feature of Aerotech''s linear positioning tables for laser processing applications. With the release of the Nmark CLS, this functionality is now available for scanner applications. The Nmark CLS offers Position Synchronized Output (PSO) that ties laser pulses directly to galvo position. While other scanner controllers use time-based pulses to shutter laser light, the Nmark CLS PSO allows true position-based triggering. The ability to accurately trigger the laser as a function of position removes the need to program mark, jump, and polygon delays, resulting in reduced programming complexity. By using the Position Synchronized Output functionality, scanner-based processes can now be programmed in the same fashion as traditional X/Y stage-based applications.

The Infinite Field of View feature seamlessly synchronizes servo and scanner motion under one controller environment to allow fast scanner positioning over the entire servo travel, eliminating galvo field of view constraints. The Nmark CLS has two high-power drive circuits, one for each axis in the scanner, that are optimized to get the peak performance from the AGV product family.
