What Is a Galvo Laser and How Does It Work?

A galvo laser is a type of laser system that uses galvanometer-based mirror motors to rapidly direct the laser beam across a working surface. Unlike traditional gantry systems, galvo lasers rely on high-speed mirror movement for beam deflection, offering faster and more precise marking or engraving.

The core of this system lies in the scan head, which houses the galvo motors, mirrors, and focusing lens. The scan head controls the beam's path with incredible speed and precision, making galvo scanning the preferred solution for high-throughput applications.

Advantages of Galvo Scanning with Professional Scan Heads

Galvo scanning offers several key advantages over mechanical movement systems:

  • High-Speed Processing: Scanning speeds up to 10,000 mm/s

  • Ultra-Precise Marking: Excellent beam accuracy ensures fine detail work

  • Non-Contact Operation: Reduces wear and tear, increasing system longevity

  • Compact Design: Galvo scan heads are compact and integrate easily into production lines

  • Flexible Patterns: Ideal for logos, QR codes, barcodes, serials, and deep engraving

By combining a high-performance scan head with a stable galvo laser source, manufacturers can drastically improve production efficiency without compromising on quality.

Where Is Galvo Scanning Used?

Galvo laser systems are used in industries requiring high-precision, high-speed marking or cutting:

Industry Application
Electronics PCB marking, chip engraving, connector codes
Automotive VIN codes, part identification
Medical Devices Surgical tool and implant marking
Packaging Dynamic text, QR/barcode marking
Jewelry Intricate designs, micro-engraving

Especially when equipped with advanced scan head technology, galvo lasers become essential tools in modern smart factories.

Choosing the Right Galvo Laser and Scan Head

When selecting a galvo laser system, it's essential to consider:

  • Wavelength compatibility: Fiber, CO₂, or UV galvo laser

  • Field of View (FOV): Determines the size of the working area

  • Spot Size: Affects marking resolution

  • PSO/encoder support: For synchronized motion in dynamic applications

  • Durability of scan head mirrors: Especially important for high-power applications

High-quality scan heads from brands like JCZ, Scanlab, and Raylase ensure long-term reliability, thermal stability, and high-speed performance.

The Future of Galvo Scanning in Laser Processing

With the rise of Industry 4.0 and smart manufacturing, galvo scanning is becoming even more essential. New developments such as:

  • AI-assisted beam path optimization

  • Closed-loop feedback scan heads

  • Real-time image processing with vision systems

are pushing the boundaries of what galvo laser systems can do.

Conclusion – Maximize Efficiency with the Right Scan Head and Galvo Technology

If you're looking to enhance speed, precision, and reliability in your laser processing, a galvo laser system with a high-quality scan head is your best choice. The advantages of galvo scanning are clear: non-contact precision, high-speed throughput, and unmatched marking quality across a wide range of industries.

Whether you're marking electronics, cutting thin films, or engraving intricate designs, investing in the right galvo technology can take your productivity to the next level.
