Master Precision with Galvo Head Technology: The Future of High-Speed Laser Marking & Engraving

A galvo head, short for galvanometer scanner head, is a high-speed positioning device used in laser marking, engraving, welding, and cutting systems. This component controls the direction of the laser beam with extreme accuracy by using two tiny mirrors mounted on fast-moving motors—X-axis and Y-axis galvanometers—to steer the beam across a surface without physically moving the laser head.

In industries that require speed, accuracy, and repeatability, galvo head systems are the core of high-performance laser setups, replacing slower mechanical systems with electromagnetic finesse.

🧠 Why Galvo Heads Matter in Modern Industry

Galvo heads are engineered for high-volume, high-speed, and high-precision laser applications. Think of them as the steering wheel for your laser beam—only a thousand times faster and far more accurate.

🛠️ How a Galvo Head Works: Breaking It Down

A galvo system typically includes:

• Galvanometer Motors: Tiny motors that rotate mirrors rapidly.

• Mirrors: Two high-reflective mirrors mounted to adjust beam on X and Y axes.

• Drive Electronics: Control boards that translate software instructions into mirror movement.

• Lens (F-Theta): Keeps the beam focused and distortion-free across the marking area.

The laser beam remains stationary, while the galvo mirrors redirect it to the target. This minimizes latency and allows for intricate patterns at lightning speed.
