Speedy galvo-based z-scanner excelliSHIFT

Numerous laser applications demand highly dynamic laser spot motion across complex three-dimensionally formed surfaces. Typical applications are: ultra-fast 3D processing, micro machining, marking of curved surfaces and deep engraving. Precisely for this need, SCANLAB developed a new type of z-scanner that extends a 2D scan system into a 3D system. The excelliSHIFT is perfectly suited 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 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 mould-making. One potential application is functionalization of three-dimensional surfaces for vehicle construction.More products
