A fiber laser scan head galvanometer is a device used in laser marking and engraving systems to control the movement of the laser beam.

It is composed of a galvanometer and a scan head.
A galvanometer is a type of electrical motor that is used to control the position of a moving element, in this case, the scan head. It is typically a small, high-speed motor that can rotate at high speeds to control the movement of the scan head.
