Ultraviolet laser marking machine belongs to the series of laser marking machines, and is currently a relatively advanced laser marking equipment in China. However, it is developed using a 355nm ultraviolet laser. Compared with infrared lasers, this machine uses third-order intracavity frequency doubling technology. The 355 ultraviolet light has a very small focus spot. The effect of marking is to directly break the molecular chain of substances through a short-wavelength laser. , To greatly reduce the mechanical deformation of the material, although it is deformed by heat (cold light), it is mainly used for ultra-fine marking and engraving. It is especially suitable for marking, micro-holes, and high-speed division of glass materials for food and medical packaging materials. Application industries such as complex pattern cutting on silicon wafers.

It is used for marking and surface treatment of various glass, TFT, liquid crystal screens, plasma screens, textiles, thin ceramics, single crystal silicon wafers, IC grains, sapphire, polymer films and other materials.
