Presentation of the equipment's characteristics

The LM2206-GST Auto-Focus Galvo Scanner is a high-speed scanning head with an integrated automatic focusing module, engineered for efficient and repeatable laser marking. It delivers stable operation, high positioning accuracy, fast marking performance, and strong anti-interference capability—ideal for production environments where speed and consistency matter.

With one-click autofocus positioning, the scanner can quickly lock onto a preset focus height, significantly improving setup efficiency and reducing manual adjustments. Overall performance is benchmarked to meet the technical level of comparable domestic and international products.

processed samples

  • Differential photoelectric position feedback
    Accurately detects rotor position to achieve excellent linearity, low drift, high resolution, and high repeatability.

  • Precision load design for 10 mm mirrors
    High assembly accuracy, optimized structure, low static friction, and minimal zero drift help ensure strong dynamic performance and stable scanning.

  • Built-in protection for reliable operation
    Supports overload, overcurrent, and reverse-polarity protection to improve system safety and uptime.

  • Improved stability against common drift/interference issues
    Designed to address typical problems such as motor temperature drift, signal interference, and zero-position drift.

  • Auto-focus mode with one-click fast positioning
    Quickly reaches the preset focal height to streamline workflows and boost productivity.

  • Convenient hardware control
    Auto-focus buttons are integrated on the top of the mounting bracket for easier on-site operation.
