Galvo Head Technology: Understanding 2D and 3D Galvo Heads for Laser Systems

In the world of laser marking, engraving, and cutting, galvo head technology plays a vital role in precision, speed, and versatility. Whether you’re using a 2D galvo head for flat-surface marking or a 3D galvo head for complex contours and variable focus levels, choosing the right scanning system is key to maximizing laser performance.

What Is a Galvo Head?

A galvo head, short for galvanometer scanner head, is a component used in laser systems to direct the laser beam via rapidly moving mirrors. Controlled by servo motors, the galvo head precisely guides the laser beam to the desired position on the target surface at high speeds — making it essential in industrial applications like marking, welding, cleaning, and additive manufacturing.

Difference Between 2D Galvo Head and 3D Galvo Head

Applications of Galvo Heads

Galvo head systems are widely used across multiple industries due to their unmatched speed and accuracy:

2D Galvo Head Applications:

• Barcode & QR code laser marking

• Nameplate engraving

• High-speed plastic part coding

• Logo etching on metal tools

3D Galvo Head Applications:

• Engraving curved surfaces like jewelry, cups, molds

• Deep engraving with dynamic Z-axis tracking

• Precision micromachining in aerospace and electronics

• 3D relief sculpting on wood, plastic, or stone

How Galvo Heads Improve Laser System Efficiency

Using a galvo head ensures:

• Faster scanning speeds (up to several meters/second)

• High positional accuracy (±0.01 mm or better)

• Reduced wear compared to mechanical movement systems

• Digital control compatibility with leading laser software

With the right controller and laser source, both 2D galvo heads and 3D galvo heads offer scalable solutions for both entry-level and industrial-grade laser machines.

Choose the Right Galvo Head for Your Laser System

When deciding between a 2D galvo head and a 3D galvo head, consider:

• Your material type and surface shape

• The desired engraving or marking depth

• System budget and space limitations

• Required laser source compatibility

We offer a wide range of galvo scanner heads compatible with fiber lasers, CO₂ lasers, and UV lasers, backed by reliable servo technology and high-reflection mirrors. Our 3D galvo heads come with Z-axis control modules, F-theta lenses, and software packages for dynamic focal control.
