the new premium scanning standard SCANLAB's excelliSCAN scan head sets new high-end standards for meeting the most challenging demands. Its groundbreaking SCANahead control technology and field-proven dynAXISse digitalencoder galvanometers attain previously unreachable dynamic performance and precision. This translates to enormous gains in productivity and process accuracy. Innovative excelliSCAN design features: New SCANahead control • Full utilization of scanner dynamics for higher throughput • No unwanted necking effects when rapidly processing circles • Universal tuning optimized for all applications dynAXISse digital-encoder galvanometers • Maximum linearity and minimum position noise ensure highest positioning accuracy • High long-term stability even with ambient temperature fluctuations and 24/7-operation Housing innovations • Enhanced thermal management for higher load resilience • Variant with active air cooling available for applications that don't allow water as a coolant • Increased tightness (IP56) and robustness SCANLAB offers excelliSCAN in combination with the RTC6 PCIExpress control board. With its substantially increased processing power and optimum support of SCANahead control technology, the RTC6 opens up new system-control p

excelliSCAN SCANahead control SCANahead principle of operation Conventional control SCANahead control allows excelliSCAN to deliver full acceleration even at slow scan speeds (i.e. with minimum acceleration duration ta). Pre-computed set-point trajectories make this possible. Computation occurs in real time, offset by the look-ahead time tp, prior to actual execution. Limiting trajectory acceleration to the scanner axes' full acceleration produces a set-point trajectory (blue curve) that the SCANahead control can track without tracking error (red curve). Thus, the galvos' dynamic...

• Concept fundamentally eliminates it. Processing circles, arcs Tracking error Conventional control • Acceleration time is constant at all scan speeds: acceleration potential isn't fully utilized. • Necking effects (caused by tracking error) need to be offset by adjusting circle diameters. • Finite, constant value • Precise image field correction even at high speeds SCANahead control • Scanner axis acceleration always at maximum: acceleration time is minimized. • Necking effects avoided. • Limits precision of image field correction at high speeds • Only one tuning needed. Optimum...
