Control (and principle of operation)

Scan systems transform lasers into highly flexible processing tools. The range of functionality strongly depends on both the controller and the scan system's servo electronics. The servo electronics in SCANLAB's scan systems not only dynamically positions the laser beam, but also provides status signals. This status information returned by the scan head can be evaluated not just for system monitoring purposes, but also for optimization.

SCANLAB offers a variety of RTC control boards that enable synchronous control of scan systems, lasers and peripheral equipment.

Scheme of operation for controlling a scan system:

Deflection of the laser beam occurs at the scan mirrors, which are quickly and precisely positioned by galvanometer scanners. SCANLAB's scan heads integrate all components, including electronics, into a compact, sealed housing.

To focus the laser beam, an objective is used at the scan system's beam exit and/or a focusing unit is used at the beam entrance. SCANLAB offers a variety of software for laser process control and vision analysis.
