Galvo scanner for laser micromachining and additive manufacturing

With the "AGV-SPO", Aerotech presents a new high-performance galvo scanner. It offers a larger field of view than conventional 2D scanners, reduces laser spot distortion and, thanks to a wide range of mirror surfaces, can be used flexibly for a large number of laser wavelengths. As a result, the laser scanner offers an extremely wide range of applications from additive manufacturing to medical technology.

With just one pivot point for X and Y deflection, the scanner significantly increases the field of view and thus reduces laser spot distortion in critical applications in laser micro-processing. Due to the special optical design, the entrance pupil of the laser beam falls simultaneously on the X and Y deflection mirrors, which increases the effective numerical aperture of the scanner system. The design instantly increases the field of view for a given focal length and reduces laser spot distortion throughout the work area. With the scanner, larger parts can now be processed more quickly and with improved uniformity.

Foam laser technology from Arpro to a depth of 1,5 mm

For the scanner, there are a variety of mirror coatings and focusing optics for a variety of commonly used laser wavelengths and focal lengths. But also customized 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 thus continuously good work results even with high laser power or highly dynamic motion profiles.
