In the precision laser world, speed and accuracy are essential. That’s where galvo scanners come into play. Whether you’re involved in laser engraving, marking, welding, or cutting, a reliable galvo system significantly enhances productivity, especially when paired with a high-performance galvo head laser.
What Are Galvo Scanners?
Galvo scanners (short for galvanometer scanners) are fast-moving mirror systems that control the path of a laser beam using electromagnetic motors. These scanners are widely used for:
Laser marking
Engraving
3D printing
Material processing
They enable high-speed deflection and precise beam positioning, making them ideal for industrial applications requiring speed without compromising quality.
Benefits of a Galvo Head Laser
A galvo head laser is the critical component that includes the scanning mirrors and drivers. When integrated into a laser system, it brings several advantages:
High-speed performance: Ideal for rapid marking or engraving tasks
Excellent precision: Maintains accuracy even at high scanning rates
Compact size: Fits into various automated systems
Long life & low maintenance: Designed for industrial durability
Whether used in fiber laser or CO₂ laser systems, the galvo head laser delivers consistent beam control and reliability.
Understanding the Galvo System
A complete galvo system includes:
Galvo head (scanner)
Laser source
Control software
F-theta lens
This system architecture allows the laser beam to be moved at extremely high speeds over the working surface. Compared to gantry-style systems, a galvo system does not rely on physical movement of the workpiece or the laser itself, resulting in faster cycle times.
Applications of Galvo-Based Systems
Galvo scanners are critical in various sectors:
Electronics – PCB marking, traceability codes
Medical devices – Serial number marking, scale etching
Jewelry and crafts – Intricate engraving on metals
Packaging – Date codes and lot numbers on high-speed lines
Thanks to their adaptability, galvo head laser systems can be used in desktop, portable, or industrial inline configurations.
Final Thoughts
For any business looking to scale laser precision and speed, investing in a robust galvo system is a smart move. Whether you need a compact galvo head laser for a desktop engraver or a full-fledged production-grade galvo scanner, the technology ensures efficient, high-speed performance across a wide range of materials and industries.
