The ultraviolet laser marking machine belongs to the series of laser marking machines, but it is developed using a 355nm ultraviolet laser. The machine uses third-order intra-cavity frequency doubling technology to compare with an infrared laser. The 355 ultraviolet light spot is extremely small and can be To a large extent reduce the mechanical deformation of the material and the processing heat effect is small because it is mainly used for ultra-fine marking and engraving, especially suitable for marking food, beverage packaging materials, micro-holes, high-speed division of glass materials and silicon Application areas such as complex wafer cutting of wafers.
