What is 355nm uv lasers and what are its characteristics

Ultraviolet laser marking machine is also called purple laser marking machine, cold light laser engraving machine or UV laser marking machine, and it is widely used now.

Ultraviolet laser marking machine belongs to a series of products of laser marking machine, but it is developed with 355nm ultraviolet laser. Compared with infrared laser marking equipment, the machine adopts third-order intracavity frequency doubling technology, and the 355 ultraviolet light focusing spot is extremely small. , can greatly 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 laser marking of food, pharmaceutical packaging materials, micro-holes, and high-speed glass materials. Dividing and complex pattern cutting of silicon wafers and other application areas.

Ultraviolet laser marking machine is a series of laser marking machines, so the principle is similar to that of laser marking machine, and it is used to mark the surface of various materials with laser beams. The effect of marking is to directly break the molecular chain of the material by the short-wavelength laser (different from the evaporation of the surface material produced by the long-wave laser to expose the deep material) to reveal the pattern and text to be etched.

Due to the extremely small focusing spot and the small processing heat affected zone, the ultraviolet laser can carry out ultra-fine marking and laser marking of special materials. It is a product for customers who have higher requirements for laser marking effect. In addition to copper materials, UV lasers are suitable for a wider range of materials. Not only the beam quality is good, the focusing spot is smaller, and ultra-fine marking can be realized; the scope of application is wider; the heat-affected area is extremely small, no thermal effect will occur, and there will be no material scorching problem; marking speed, high efficiency; machine performance Stable, small size, low power consumption and other advantages.

The UV laser marking machine is mainly based on its unique low-power laser beam, which is especially suitable for the high-end market of ultra-fine processing. Fine effect, firm marking and cleaning, better than ink coding and no pollution; flexible pcb board laser marking and scribing; silicon wafer micro-hole and blind-hole processing; LCD liquid crystal glass two-dimensional code laser marking, glassware surface Punching, laser engraving of metal surface coating, plastic buttons, electronic components, tempered glass, gifts, communication equipment, building materials and other laser marking processing.
