The AGV-SPO single pivot-point galvanometer scanner from Aerotech (Pittsburgh, PA) enables a larger field of view and reduced spot distortion for critical laser micromachining applications. A unique optical design effectively controls the beam entrance pupil to be coincident for the X and Y scanner motion, increasing the effective numerical aperture of the scanner system. This design directly enables a larger field of view for a given focal length and reduces spot distortion over the entire working area. These advantages allow the AGV-SPO to process larger parts faster and with greater consistency. Other features include:
- 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 ability to 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.
- Advanced 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.
- Aerotech’s Infinite Field of View (IFOV) function, which seamlessly combines servo and scanner motion to extend the marking capability of the scanner across the entire travel range of the servo stages. This eliminates stitching errors that can occur in a more traditional move-expose-repeat process.
