New Galvo Scanner for Laser Micromachining and Additive Manufacturing

Ramsdell – 30th January 2019 – Aerotech, provider of high-performance motion control and positioning systems, introduces the AGV-SPO, a new high-performance Galvo Scanner. It offers a larger field of view than conventional 2D scanners, reduces laser spot distortion, and 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.

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. 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. With the new Galvo Scanner, even larger parts can now be processed faster and with improved uniformity.

Always on the right wavelength

Aerotech’s AGV SPO scanner provides a range of mirror coatings and focusing optics to support a variety of commonly used laser wavelengths and focal lengths. Also, 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.

Well positioned laser scanning without stitching

The laser scanner benefits from the high performance of the Aerotech’s controllers with their advanced motion control and position synchronised output (PSO). In addition, path control functions such as acceleration limitation offer the ability to automatically reduce scanning speed in tight bends or small radii to minimise overshoot. In addition, the laser can also be triggered based on the position feedback of the mirrors via the PSO. This ensures a consistent laser spot overlap when the scanner changes speed. Aerotech's Infinite Field of View (IFOV) feature seamlessly combines servo drive and scanner motion to extend laser marking across the entire servo axis travel range. This avoids stitching errors that can occur during the move expose repeat process.

Aerotech Inc., headquartered in Pittsburgh, USA. is a private, family-owned, mid-sized company. Founded in 1970 by Stephen J. Botos, Aerotech designs and manufactures the world's most powerful motion control and positioning systems for industrial, scientific and research customers. In the spirit of a family business, the owners continue to attach the utmost importance to an open and trusting relationship with customers, business partners and employees. In Germany, the medium-sized company is represented by its own subsidiary, Aerotech GmbH, headquartered in Fürth near Nuremberg, Franconia. In addition to sales and service activities, the Fürth office is also responsible for the customized assembly of positioning systems for the European market.
The innovative and high-precision motion solutions meet all the critical requirements needed for today's demanding applications. They are used wherever high throughput is required, e.g. with medical devices and life science applications, in semiconductor and flat screen production, in photonics, automotive, data storage, laser processing, aerospace, electronics manufacturing, as well as in testing and inspection through to assembly.
Aerotech provides world-class technical support and service with its advanced analysis and diagnostic capabilities. If a standard product is not suitable for an individual application, Aerotech’s many years of expertise and experience enable the manufacturer to supply special motion components and systems. The manufacturing capacity for custom applications is complemented by experience in supplying systems for vacuum and clean room operation
Aerotech has full-service offices in Germany (Fürth), United Kingdom (Ramsdell), China (Shanghai City), Japan (Chiba) and Taiwan (Taipei City). Aerotech currently employs approximately 500 people worldwide. http://www.aerotech.com
