Galvo Scanner with Large Field of View

Aerotech released the AGV-SPO, a new Galvo Scanner for laser micromachining and additive manufacturing. With a larger field of view than 2D scanners, it reduces laser spot distortion in critical laser micromachining applications and is flexible enough to accommodate a wide range of laser wavelengths thanks to a wide variety of mirror surfaces. The AGV-SPO includes only one pivot point for X and Y deflection to increase the field of view. 


Customizable options to be on the right wavelength


Through its special optical design, the entrance pupil of the laser beam coincides with the X and Y deflecting mirrors, increasing the effective numerical aperture of the scanner system. The mirror coatings and focusing optics provided by the scanner help support a range of laser wavelengths and focal lengths. Moreover, customer-specific optics and optical mounting options can be adapted as a unique solution. Air-cooled mirrors and water-cooled motors can also be added, ensuring constant temperature conditions, even with high laser power.


A right positioned scanner that avoids stitching errors


The AGV-SPO benefits from the Aerotech’s controllers thanks to their advanced motion control and position synchronized output (PSO). Furthermore, path control functions such as acceleration limitation are available to automatically reduce scanning speed in tight bends or small radii to minimize overshoot. The laser can also be triggered based on the position feedback of the mirrors through the PSO, to grant a consistent laser spot overlap when the scanner changes speed. Last, Aerotech’s Infinite Field of View (IFOV) feature seamlessly combines servo drive and scanner motion to extend laser marking across the servo axis travel range in order to avoid stitching errors.
