Single mirror dual axis scanner
By providing two axis of motion on a single mirror surface, the VT2000 avoids abberations common in two mirror scanning devices. The scanner has closed loop feedback control for accurate postion management but can also use used in open loop for applications such as laser wobble for welding.
Laser processing equipment suppliers rely on the VT 2000 to provide oscilling patterns including circles, waves and zigzag wobble for better quality welds and defect free weld joints.
