Due to its extremely small focused spot and small processing heat affected zone, ultraviolet laser can be used for ultra-fine marking and special material marking, making it the preferred product for customers with higher requirements for marking effect. UV laser is suitable for processing a wider range of materials besides copper. Not only is the beam quality good, the focused spot is smaller, and it can achieve ultra-fine marking; The scope of application is broader; The heat affected area is extremely small, and there will be no thermal effect or material burning problem; Fast marking speed and high efficiency; The advantages of stable overall performance, small size, and low power consumption.
