Galvanometer A galvanometer, also known as a galvo scanner or scanning head, is an optical component used in laser engraving systems to direct and control the laser beam with high speed and precision. Galvanometers consist of a mirror mounted on a rotating shaft and electromagnetic coils that deflect the mirror in response to electrical signals. By rapidly adjusting the position of the mirror, galvanometers steer the laser beam across the material surface, allowing for fast and accurate engraving of intricate designs, text, and graphics. Galvanometer-based scanning systems are commonly found in laser marking, etching, and micro-machining applications requiring high-speed and high-resolution engraving capabilities.’ |
