LSSL Series 3D Marking Heads

1. LSSL excelliSHIFT 3D Marking Heads

Our new excelliSHIFT extends a 2D scan head into a highly dynamic 3D system. Based on tried-and-proven galvanometer technology, its completely new design drastically improves dynamic performance compared to conventional z-axes. The Z-scanner is no longer a limiting factor, so that identical acceleration can be achieved in all in all three spatial directions. This opens up entirely new possibilities for laser processing of 3-dimensional, complexly-shaped surfaces. Moreover, the new technology uses no transmissive optical components. That means dispersion effects are avoided when working with different wavelengths, and thermal-lens effects are minimized, too.

2. Z-Scanner Module

We also offer Z-Scanner modules. The varioSCAN can extend XY scan systems into 3D beam deflection systems. The laser focus is guided along the contour of the workpiece being processed, thus enabling processing in three dimensions.

During the scanning process, a perging optic in the varioSCAN is positioned with high dynamics along the optical axis with respect to a stationary focusing optic. This produces a change in the system’s overall focal length, synchronized with the mirror motion. The varioSCAN focusing unitcan thereby expand 2D scan systems into 3-axis scan systems.

1. LSRM-QPT: 3D Post-Scanning Solution

(Refer to LSRM-Q datasheets for 2D marking heads)

This solution includes a 2D galvoscanner system LSRM-Q Series, a dynamic focusing unit Proton Series, F-theta lens and a galvo system controller LSRM-UMC4. It uses the post-objective scanning technology, the working volume is about 150*150*45 with the FL 210mm F-theta lens. The advantages are fast marking speed, small focal spot and low power loss.
