Galvo scanners are at the heart of modern laser marking, engraving, and welding systems, playing a critical role in achieving speed, accuracy, and precision. If you're searching for cutting-edge galvo scanner technology, LaserChina offers one of the most comprehensive and reliable selections on the market—blending innovation, performance, and engineering expertise.

This blog dives deep into what a galvo scanner is, why LaserChina’s solutions stand out, and how this technology enhances industrial laser processes across diverse sectors.

What is a Galvo Scanner?

A galvo scanner (short for galvanometer scanner) is an optical positioning device that uses galvanometer motors to move mirrors, directing laser beams with high speed and accuracy. These devices are essential in:

• Laser marking and engraving

• Laser cutting

• Welding systems

• Micromachining

• Additive manufacturing

The key advantage? A galvo scanner rapidly deflects the laser beam over a workpiece without needing to move the actual laser head or material.

• Enhanced Throughput: High-speed scanning improves production cycles.

• Minimal Maintenance: Engineered for reliability, reducing long-term costs.

• Software Integration: Compatible with EZCAD and proprietary systems for seamless workflow.

How Galvo Scanners Work – Simplified

A galvo scanner uses two rotating mirrors, typically mounted at 90-degree angles. Here's a basic flow:

1. X-axis mirror moves the laser beam left or right.

2. Y-axis mirror moves it up or down.

3. F-Theta lens flattens the field to maintain consistent focus across the scan area.

This system allows extremely fast, precise control of the laser’s position—far quicker than moving a mechanical stage.

Choosing the Right Galvo Scanner from LaserChina

LaserChina provides several models tailored to specific needs:

• Standard Series: Ideal for general laser marking

• High-Speed Series: Optimized for large-volume manufacturing

• Large Field Series: Suitable for big work areas and deep engraving

• UV Galvo Series: Designed for sensitive materials requiring high resolution

Use this checklist when selecting a model:

• Required working area

• Target material

• Desired scan speed

• Laser type in use

• Application type (engraving, welding, drilling)

FAQs About Galvo Scanners

Q: Can I use any galvo scanner with a fiber laser?

A: No. You must ensure the scanner’s optics are coated for 1064nm wavelength, which is typical for fiber lasers. LaserChina offers specialized models for each laser type.

Q: What lens should I use with a galvo system?

A: F-Theta lenses are the standard, offering a flat field and uniform focus. LaserChina provides lens selection based on your work area and laser wavelength.

Q: Is calibration necessary?

A: Yes. Calibration ensures accurate beam positioning. LaserChina scanners come pre-calibrated, but periodic checks are recommended for industrial settings.

Q: Are galvo scanners suitable for 3D applications?

A: Advanced models from LaserChina support Z-axis control and dynamic focusing, making them suitable for 3D marking and engraving tasks.

Expert Tips for Using Galvo Scanners Efficiently

• Regularly clean lenses and mirrors to avoid power loss.

• Use proper cooling to maintain consistent performance.

• Avoid exceeding scan angles beyond manufacturer specs.

• Update firmware/software regularly to ensure stability and feature access.
