What is a Galvanometer scanner?

The galvano scanner is one way to scan lasers and the like. The optical elements (mirrors and lenses) attached to the rotating shaft are rotated at high speed by an electromagnetic motor, etc., and the servo driver controls the motor at high speed and with high accuracy based on the output from the position sensor to realize the scanning function. By using two galvano scanners for X and Y, laser scanning can be performed in a two-dimensional plane. There is also a 3D galvano scanner that can scan three-dimensionally by adding a galvano scanner in the Z direction.

Application of Galvanometer scanner

It is used for high-speed and high-precision laser drilling, laser marking, welding, and laser scanning of 3D printers using trendy photo-curing resins. It is used for machining parts that require micron-level accuracy.
