Leading OEM manufacturer of laser scan solutions SCANLAB GmbH has launched its new z-axis generation varioSCAN II, an innovative system design with new bearing technology that enables the compact z-axis to be integrated into a laser machine in any mounting orientation.
The additional flexibility is said to simplify the implementation of different laser system concepts for machine builders. SCANLAB GmbH says precise workpiece processing in three dimensions requires highly dynamic positioning of the laser focus along the optical z-axis. With the addition of focusing units, xy scan systems can be easily transformed into 3D beam deflection systems, allowing the laser focus to be guided along the exact contour of the workpiece being processed.
The varioSCAN product line is said to be ideal for applications requiring f-theta lenses as well as applications for which these costly lenses are unavailable, in which case the focusing system provides a plane focusing surface in addition to z-adjustment of the focus. As well as the processing of three-dimensional surfaces, classic fields of application requiring z-axis manipulation include additive manufacturing (3D printing) and laser cutting.
In many of these applications, there is a trend towards higher laser powers, the use of ultrashort pulse lasers and the demand for improved image quality and positioning accuracy.
In developing the new varioSCAN II, SCANLAB GmbH says the focus was on exactly those requirements, with the mechanical design, in particular, being optimised for technical cleanliness. The configuration of the optics is tailored to customer requirements, for example in terms of the z-travel, laser wavelength and beam diameter.
The new lens designs, as well as the use of low-absorption optics and premium coatings, open up new possibilities for users to improve their individual laser processes.
SCANLAB GmbH says switching to the new varioSCAN II z-axis generation is simple and efficient, as all mechanical and electrical interfaces of the focusing system are designed as a drop-in replacement for the established previous model.
