0 AEROTECH A New Era in Galvo Performance

When Precision Matters Aerotech's AGV scanners are designed with high-resolution feedback devices that are thermally stable and exhibit virtually no gain or offset drift. Control electronics are completely separated from the scanner to provide the highest levels of thermal stability. The Nmark® GCL uses advanced interpolation electronics to provide up to 26-bits of effective resolution. Advanced calibration techniques enable accuracies at the image plane to the single-digit micrometer level. Infinite Field Of View (IFOV) It is common practice to use servo axes in conjunction with scanners...

The AGV and GCL combine to form a high-throughput solution in applications like via drilling. The image above shows the AGV/GCL performing multiple 30 pm diameter circles at a rate of 3000 times per second, with less than 1.5 pm of tracking error. Continued Excellence in Combined Scanner/Servo Motion Aerotech's Nmark GCL closed-loop scanner drive for the Automation 3200 motion platform allows for direct conjoined control of galvo scanner and servo motion for micromachining and marking of parts of unlimited size and complexity. The 100% digital scanner control removes the need for...
