17 Mar 2006 Dynamic Focusing Unit: The Future of Laser Welding The new varioSCAN FC further demonstrates SCANLABs leadership in the multi-kilowatt scan solution market.
The varioSCAN FC is a dynamic focusing unit that quickly and precisely positions the laser focus along the optical axis. Combining the varioSCAN FC with a powerSCAN-series 2D scan system forms an exceptionally flexible 3D scan solution for applications such as remote laser welding.
High-power fiber-coupled solid-state lasers easily attach directly to the varioSCAN FC via commonly available fiber connectors. Air and water cooling connections facilitate stable and safe varioSCAN FC operation with laser powers in excess of 5 kW.
The varioSCAN FCs variable collimator ensures virtually constant focus diameter throughout the entire working volume. The collimators lens system is positioned quickly and precisely by SCANLABs new linAXIS linear drive. The linAXIS combines extended range of motion with extremely high acceleration values, even when positioning heavy loads.
Selecting appropriate optical elements allows the varioSCAN FC to be adapted to various fiber types, fiber connection systems, and image fields.
The varioSCAN FC and powerSCAN can be easily controlled via SCANLABs RTC PC interface boards. |
