Laser Galvo scanners are essential tools in the world of laser technology, particularly in applications involving laser marking, engraving, and cutting. Understanding their mechanics and functionality is crucial for industry professionals and enthusiasts alike. In this article, we delve into the intricacies of laser Galvo scanners and how they operate, supported by insights from industry experts.

What is a Laser Galvo Scanner?

A Laser Galvo scanner, or galvanometer scanner, is a device that uses mirrors mounted on galvanometer motors to direct laser beams with high precision. Unlike traditional laser systems that may move the entire laser source, Galvo scanners achieve fast and accurate movement by adjusting the mirrors to manipulate the laser’s path.

How Does a Laser Galvo Scanner Work?

The working principle of a laser Galvo scanner can be broken down into several key components:

• Laser Source: The initial beam of light is generated by a laser, which can vary in type (e.g., fiber, CO2, solid-state).
• Galvanometer Mirrors: These mirrors are controlled by electrical signals that adjust their angle, allowing the laser beam to be directed precisely on the target material.
• Control System: A computer interface provides the necessary software to translate design files into motion commands for the galvanometer.
