OEM laser deflection and positioning systems manufacturer SCANLAB GmbH now adds even more materials-processing power control capabilities to XL SCAN, the combined solution for simultaneously controlling scan heads and XY stages. For specialized industrial ultra-short pulse (USP) lasers, these new features and algorithms offer control capabilities such as: constant pulse intervals, deflection-angle-dependent energy densities or controlled laser power settings. The virtually limitless scanned image field has proven itself in practice and demonstrably boosts throughput, e.g. in film processing, PCB drilling and large-scale laser marking.<\/p>\n

Laser processing is often constrained by a scanner\u2019s image field. Large-scale processing traditionally gets performed stepwise via individual image fields, called \u2018tiles\u2019. But this method bears the risk of longer process times and stitching errors, i.e. misaligned marking at image field boundaries. To overcome this problem, SCANLAB and ACS Motion Control last year introduced a new scan concept. XL SCAN and the jointly developed syncAXIS control software enable simultaneous control of an excelliSCAN scan head and a mechanical XY stage with two servo axes. This solution employs an RTC6 control board to transmit motion profiles to both stage and scanner. The application\u2019s precision is thereby limited solely by the stage\u2019s and scanner\u2019s precision \u2013 the control itself introduces no additional error. This concept decisively differentiates XL SCAN from competitors\u2019 systems that close a feedback loop between the scan system and stage, but are constrained by very slow dynamics. A typical feedback loop\u2019s 10-\u03bcs transmission\/preview latency, together with a scanner speed of 2.5 m\/s, could already cause deviations of 25 \u03bcm.<\/p>\n

Positive Effects of Control<\/strong><\/p>\n

Larger systems can even employ multiple instances \u2013 such as two scan heads and four stages \u2013 controlled from a single PC. The new scan concept has meanwhile proven itself in diverse industrial and research organization applications, and its functionality is being further extended based on customer feedback.<\/p>\n

A new trajectory planner enables exact control of two laser parameters in conjunction with triggerable USP lasers. For users, this means a controllable pulse interval on the middle line or the inner contour of the laser track. Also available is laser power control \u2013 completely independently of scan patterns or motion speeds. Plus, syncAXIS control allows also with various deflection angles to assure a constant fluence on the workpiece.<\/p>\n

\u201cWe\u2019re positively surprised by our customers\u2019 feedback. For instance, customers\u2019 tests of XL SCAN for display fabrication and glass surface processing boosted their precision by a factor of 3 compared to other manufacturers\u2019 systems,\u201d reports SCANLAB CEO Georg Hofner regarding experience gained in recent months. \u201cAppreciably enhanced user productivity is probably a further factor behind growing demand for this combined scan solution.\u201d<\/p>\n
