**What are Galvo Mirrors?**
Galvo mirrors function as fast, motor-driven mirrors that pivot on either horizontal or vertical axes to redirect laser beams. They leverage galvanometer technology, which allows for rapid and precise positional adjustments. When paired with laser systems, these mirrors can modulate the direction of the beam accurately, enabling high-speed scanning and intricate engraving or cutting processes.
The fundamental operation of a galvo mirror relies on the control of electric currents through coil windings. As electrical signals are sent to the coils, the resultant magnetic field induces movement in the mirror, allowing it to rotate to predetermined angles. The speed and accuracy of this adjustment make galvo mirrors exceptionally suitable for applications requiring high-resolution imaging and rapid response times.
