A laser galvo system is an essential component in modern laser marking, engraving, and cutting equipment. It controls the direction of the laser beam using high-speed mirrors and precision motors. By rapidly adjusting the beam angle, galvo systems allow for accurate and fast marking over a defined surface area. LaserChina, a trusted name in laser technology, offers reliable galvo systems suitable for industrial, commercial, and research applications.

How a Laser Galvo System Works

A galvo system consists mainly of two galvanometer motors (X and Y axis), each equipped with a mirror. These mirrors move to direct the laser beam across the material surface. The speed and accuracy of the motion determine the marking quality and efficiency.

  • Laser Source: Provides the laser beam for marking or cutting.

  • Galvo Head: Contains the mirrors and motors that guide the beam.

  • F-Theta Lens: Focuses the beam onto a flat working surface.

  • Controller: Sends digital signals to control movement speed and angle.

This combination ensures that the laser follows precise patterns programmed in the control software.

Key Specifications of a Laser Galvo

When selecting a galvo system, it’s important to consider its specifications, as they directly affect performance and compatibility.

  1. Scan Speed: Typically ranges from 2,000 to 10,000 mm/s. High-speed models improve productivity.

  2. Scan Angle: Determines the working field size; usually ±10° to ±20°.

  3. Resolution: Defines how finely the laser can position the beam higher resolution gives smoother edges.

  4. Aperture Size: Commonly between 10mm to 30mm, impacting the beam size and power handling.

  5. Repeatability: Ensures consistent beam positioning, generally within a few micrometers.

  6. Cooling System: Air or water cooling maintains system stability during continuous use.

LaserChina’s galvo systems are designed for high precision, low drift, and long service life, ensuring consistent performance across demanding applications.

Characteristics and Design Features

Laser galvo systems have several distinguishing features that make them superior to traditional motion systems:

  • High-Speed Beam Movement: Allows instant repositioning without mechanical delays.

  • Compact and Lightweight Design: Saves space in laser marking machines.

  • Low Maintenance: Minimal wear due to non-contact movement.

  • Excellent Linearity: Accurate beam movement even at high speeds.

  • Compatibility: Works with fiber, CO₂, and UV laser sources.

These characteristics make galvo systems the preferred choice for industries like electronics, automotive, packaging, and medical devices.

Advantages of Using a Laser Galvo

  1. Precision and Accuracy – Achieves fine details even on complex designs.

  2. High Throughput – Performs thousands of marks per second for mass production.

Buying Guide: How to Choose the Right Laser Galvo

Before purchasing a laser galvo, consider these key points:

1. Application Needs

Determine if the galvo will be used for marking, engraving, or cutting. Different applications may require varying scan speeds and resolutions.

2. Laser Type Compatibility

Ensure the galvo system matches your laser source fiber, CO₂, or UV. Each has unique wavelength and power requirements.

3. Working Field Size

Choose based on your material size. A larger scan field is ideal for big parts, while smaller fields offer better detail.

4. Cooling and Durability

For continuous industrial use, select models with stable thermal management and durable construction.

5. Technical Support and Warranty

Reliable after-sales support ensures smooth operation. LaserChina provides technical guidance and service support for all galvo systems.
