Quantum Leap for 3D Laser Processing
As the leading provider of high quality "made-in-Germany" scan systems, SCANLAB GmbH is introducing its highdynamics excelliSHIFT z-scanner to the marketplace. Unlike conventional z-axes, the underlying patented concept fully eliminates use of transmissive elements. The resulting enormous rise in dynamic performance opens up completely new laser-processing possibilities. Moreover, this functionality is fully independent of mounting orientation, thus significantly increasing the number of degrees of freedom for machine builders and integrators. The new z-scanner is particularly compelling when used in conjunction with a 2D scanner for micro-structuring, laser engraving and processing of complex free-form surfaces.
Numerous laser applications demand highly dynamic laser spot motion across complex three-dimensionally formed surfaces. Precisely for this need, SCANLAB developed a totally new type of z-scanner that extends a 2D scan system into a 3D system. The excelliSHIFT is perfect for high-end applications in conjunction with an excelliSCAN scan head, and it's compatible with other scan heads, too.
Compared to conventional z-axes, the new z-scanner attains previously unachievable accelerations during focal shifting in the z-direction. The tried-and-proven galvanometer principle – a SCANLAB core competency and key technology – facilitates this enormous rise in dynamic performance. Thus, focal motions in the z direction are no longer a limitation for laser processing in three dimensions. The new z-scanner performs just as dynamically as a 2D scan head. The system design eliminates transmissive optics, thereby not only boosting dynamics , but also maximizing integration flexibility. These advantages accrue, for example, when designing complex machines for tool and mouldmaking. One potential application is functionalization of three-dimensional surfaces for vehicle construction.
When used with laser powers up to 120 W, no system cooling is required. For higher laser powers, a variant with air cooling is optionally available. In addition to the excelliSHIFT variant for 1030 – 1070 nm laser wavelengths, a second variant will soon be available for the 515 – 532 nm spectral range.
