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.

Features:

  • Highest reliability due to field-proven galvanometer technology
  • High-dynamic processing of complex 3D-surfaces
  • Designed without transmissive optical components
  • Flat field correction of pre-focused systems without dynamic limitations
  • Position-independent mounting

Applications:

  • Micromachining
  • Marking of curved surfaces
  • Deep engraving
  • Ultra-fast 3D processing

(2) With f-theta lens f = 160mm; at large focal lengths, corresponding higher values are achieved

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.

  • All of the above parameters are theoretical values.
  • Distance between edge of deflection unit and working surface. This distance is dependent on the product model and will vary with laser pergence and objective tolerance.
  • Actual spot size and writing speed are dependent on material and application.
