The mirror galvanometer was later improved by William Thomson, later to become Lord Kelvin. He would patent the device in 1858. Thomson reacted to the need for an instrument that could indicate with sensibility all the variations of the current in a long cable.

WebJul 1, 2024 · A Galvanometer is essentially an oscillating (it’s not really rotating as moving back and forth) mirror driven by a motor that deflects light from a laser in a straight line. However, the use of Galvanometers for 3D printing can be quite problematic as there are several fundamental issues in regards to laser intensity and speed that arise from its use.
