What is a Galvo Scanner?
A Galvo scanner is an electro-mechanical device that rapidly moves mirrors to deflect and position a laser beam across a specific area. The name "Galvo" is derived from the galvanometer, an instrument used to measure small electric currents, but in this context, it refers to a type of motor that rotates the mirrors based on electrical signals. These scanners are essential in many laser applications where high-speed beam positioning and accuracy are required.
How Does a Galvo Scanner Work?
A Galvo scanner works by utilizing one or more small, highly reflective mirrors that can pivot in response to electrical signals. These mirrors are attached to precision motors (galvanometers), which are capable of extremely rapid movement. The laser beam is directed onto these mirrors, and as the mirrors rotate, the beam is reflected at different angles. This enables the laser to quickly scan across a surface or follow a predetermined path, allowing for fast, accurate, and repeatable results.
The system typically involves two axes of motion — one mirror moves the beam along the X-axis, while the other controls the Y-axis. For more complex operations, a third axis may be added to control the focus of the beam, allowing for 3D marking or cutting.
Advantages of Galvo Scanners
- High-Speed Performance
One of the most significant advantages of Galvo scanners is their speed. These systems are capable of moving the laser beam at incredibly high speeds, making them ideal for high-throughput applications such as laser marking, engraving, or cutting. LASERCHINA’s Galvo scanners are designed to handle these high-speed requirements with unmatched precision. - Precision and Accuracy
Galvo scanners offer a high level of control over the positioning of the laser beam. This makes them suitable for tasks that require detailed and accurate marking or cutting, even at high speeds.
