The Critical Role of Scan Head in Laser Processing

In modern laser marking, engraving, welding, and cutting systems, the scan head is the core component that determines processing speed and accuracy. A high-performance laser galvo rapidly directs the laser beam across the work surface, enabling precise and repeatable laser processing.

Industrial manufacturers rely on advanced galvo scanner head technology to achieve high-speed vector marking, fine engraving, and complex pattern generation. Whether in fiber, CO₂, or UV laser systems, selecting a reliable scan head ensures stable performance and superior processing quality.

What Is a Laser Galvo and How It Works

A laser galvo (galvanometer scanner) uses high-speed rotating mirrors driven by precision motors to control laser beam positioning. The galvo scanner head converts electrical signals into angular motion, allowing the laser to scan across materials without moving the workpiece.

Compared with mechanical motion systems, a laser galvo provides:

• Extremely high scanning speed

• Micron-level positioning accuracy

• Low inertia and rapid response

• Smooth vector trajectory

• Long-term stability

These advantages make the scan head essential for industrial laser marking machines, laser engravers, and precision laser processing equipment.

Advantages of 3D Galvo Head Technology

For applications involving curved, stepped, or height-varying surfaces, a standard 2D scan head is insufficient. A 3d galvo head adds dynamic focusing capability through an additional Z-axis optical system, enabling true 3D laser processing.

A professional 3d galvo head offers:

• Dynamic focal length adjustment

• Large field processing without defocus

• Curved surface marking capability

• Deep engraving and 3D structuring

• Consistent spot size across depth

Because of these capabilities, 3d galvo head systems are widely used in automotive parts, molds, consumer electronics housings, and decorative laser texturing.
