GalvoSpiegel
GalvoSpiegel is a term used in optics to denote a galvanometer-based scanning mirror assembly that steers a light beam. The name combines the German Galvo (galvanometer) and Spiegel (mirror), reflecting its two-axis rotating mirror mechanism used to direct laser or light beams in imaging, projection, and processing systems.
Construction typically includes one or two fast-swing galvanometer motors connected to near-weightless, highly polished mirrors mounted
Key performance metrics include angular range, resonant frequency, angular resolution, linearity, drift, and settling time. Closed-loop
GalvoSpiegel assemblies are widely used in laser scanning microscopy, holography, laser projection systems, laser marking and
Origin traces to galvanometer-based scanning used in early instrumentation; modern GalvoSpiegel units emerged in the late
