Overview

This article provides a detailed introduction to the working principle of Galvo Scanner lasers, key technical parameters, and their advantages in industrial processing, with a focus on speed and precision.

Working Principle of Galvo Scanners

Galvo Scanners are widely used in laser processing, 3D scanning, medical imaging, and cosmetic applications. Their principle involves the rapid deflection of the laser beam by X/Y axis Galvo Scanners to achieve precise scanning on a two-dimensional plane. Essentially, it operates as a closed-loop control system: “voltage → mechanical deflection → optical deflection”, converting digital coordinates into physical laser trajectories.

Key Technical Parameters of Galvo Scanners

• Small Step Response Time: Reflects the dynamic response performance of the Galvo Scanner. The shorter the response time, the stronger the following ability.

• Scanning Speed: Determined by the maximum deflection frequency of the Galvo Scanner, directly affecting scanning efficiency.

• Positioning Accuracy: Typically reaches microradian levels, which directly determines the resolution of scanned patterns.

• Scanning Range: Determined by both the Galvo Scanner deflection angle and the working distance.

Advantages of Galvo Scanners in Industrial Processing

1. High-Precision Marking:
   Galvo Scanners can engrave extremely complex patterns and fonts, making them ideal for precision tasks. For example, engraving a complex vector image on wood that may take nearly an hour with other laser systems can be completed in just a few minutes with a Galvo Scanner-based laser engraving machine.

2. Large-Scale Production:
   Their speed and stability enable Galvo Scanners to efficiently handle large volumes of tasks.

3. Non-Metal Material Processing:
   Galvo Scanners can mark on a wide variety of materials, including glass, plastic, ceramics, and textiles.
