Working Principle of Laser Galvo

A galvo laser system from Scanner Optics is a high-precision tool that uses mirrors to rapidly steer a laser beam. Here's the core principle:

• Electromagnetic Dance: The laser galvo system relies on a special type of motor called a galvanometer scanner. This motor uses electromagnetic coils and a permanent magnet. When an electric current flows through the coils, it generates a magnetic field that interacts with the permanent magnet, causing the scanner to rotate.

  
  

• Mirrored Maneuvers: Mounted on the scanner are one or two tiny mirrors. By precisely controlling the current sent to the coils, the scanner rotates the mirrors, deflecting the laser beam in different directions.

  
  

• Digital Control, Agile Movements: Scanner Optics's laser galvo scan systems are typically digitally controlled. A computer sends control signals that determine the current sent to the scanner coils. This allows for highly precise and agile positioning of the laser beam.
