February 12, 2019 - Aerotech’s AGV-SPO single pivot-point galvanometer scanner enables a field of view and spot distortion for critical laser micromachining applications. An optical design effectively controls the beam entrance pupil to be coincident for the X and Y scanner motion. This design directly enables a field of view for a given focal length and reduces spot distortion over the entire working area.
The AGV-SPO is available with a selection of optical coatings and focusing optics to support a variety of commonly-used laser wavelengths and focal lengths. Customized optics and optical mounting features are available upon request. The AGV-SPO can be configured with active cooling features such as air-cooled mirrors, water-cooled motors, or both to preserve working-plane accuracy in the presence of thermal disturbances caused by the laser and aggressive motion profiles.
The AGV-SPO utilizes Aerotech’s motion and Position Synchronized Output (PSO) capabilities. Contouring functions such as Acceleration Limiting can be used to automatically reduce speeds in tight corners or small radii to minimize overshoot. The laser can be triggered based on the position feedback of the mirrors with PSO to ensure consistent spot overlap as the scanner changes speed.
