Single Mirror
Dual Axis Scanner
Two-Axis Motion on a Single Mirror Surface
By providing two axes of motion on a single mirror surface, the VT2000 avoids aberrations common in two-mirror scanning devices. The scanner has closed loop feedback control for accurate position management but can also be used in open loop for applications such as laser wobble for welding.
