A galvo in laser refers to a galvanometer, a critical component in high-speed laser scanning systems. Galvanometers are small motorized mirrors that precisely control the direction of a laser beam, allowing for fast, accurate, and repeatable marking, engraving, or cutting.
In modern laser systems, such as fiber lasers, CO2 lasers, or UV lasers, galvos are widely used to create complex patterns, text, and images at high speeds, making them essential for industrial, electronics, jewelry, and packaging applications.
How a Galvo Works in a Laser System
A laser galvo consists of two mirrors mounted on galvanometers: one controls the X-axis, and the other controls the Y-axis. When a laser beam is directed onto these mirrors, the galvanometers quickly adjust the angles of the mirrors, steering the beam across the target surface with extreme precision.
Key points about galvos in lasers:
High-Speed Scanning: Can process hundreds of characters or images per second.
Precision: Capable of micrometer-level accuracy for intricate designs.
Non-Contact Processing: No physical contact with the material, reducing wear and contamination.
Applications of Laser Galvos
Galvo lasers are widely used across industries:
Electronics: Marking PCBs, microchips, and semiconductor wafers.
Jewelry: Engraving intricate designs on metals like gold, silver, and platinum.
Automotive: VIN marking, serial numbers, and logos on car parts.
Medical Devices: Engraving surgical tools, implants, and precision instruments.
Packaging Branding: High-speed marking on bottles, cans, and plastic products.
Advantages of Using Galvo in Laser Systems
Fast Production: Rapid scanning reduces processing time.
High Precision: Accurate beam control ensures detailed engraving or marking.
Versatility: Works on metals, plastics, glass, and coated surfaces.
Durable Marking: Laser markings are permanent and wear-resistant.
Automation-Friendly: Can be integrated into production lines for large-scale manufacturing.
Conclusion
A galvo in laser systems is a key technology that enables speed, precision, and reliability in industrial laser marking and engraving. Whether for electronics, jewelry, automotive, or medical applications, a laser system with a galvo ensures efficient and high-quality results, making it a must-have for modern manufacturing.
