Galvo scanner has large field of view for laser micromachining, 3D printing

January 31, 2019 // By Julien Happich
With just one pivot point for X and Y deflection, Aerotech’s AGV-SPO Galvo Scanner significantly increases the field of view, reducing laser spot distortion in critical laser micromachining applications.

It is flexible enough to accommodate a wide range of laser wavelengths thanks to a large variety of mirror surfaces. As a result, the laser scanner is suitable for a wide range of applications, from additive manufacturing to medical devices. Due to the 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 design immediately increases the field of view for a given focal length and reduces laser spot distortion throughout the working area, enabling larger parts to be processed faster and with improved uniformity. Customer-specific optics and optical mounting options can be adapted as a special solution. Optional air-cooled mirrors and/or water-cooled motors ensure constant temperature conditions and continuously good work results even with high laser power or highly dynamic motion profiles.
