Features: The working principle of the laser galvanometer is to incident the laser beam on the two mirrors (scanning mirrors), and use the computer to control the reflection Angle of the mirror, the two mirrors can be scanned along the X and Y axis respectively, so as to achieve the deflection of the laser beam, so that the laser focus with a certain power density moves on the marking material according to the required requirements, thus leaving a permanent mark on the surface of the material. The focused spot can be either circular or rectangular.
