Was sind 355-nm-UV-Laser und was sind ihre Eigenschaften?

UV-Laser-Markiermaschine wird auch als Lila-Laser-Markiermaschine, Kaltlicht-Laser-Graviermaschine oder UV-Laser-Markiermaschine bezeichnet und ist heute weit verbreitet.

Die UV-Laser-Markiermaschine gehört zu einer Reihe von Produkten der Laser-Markiermaschine, wurde jedoch mit einem 355-nm-Ultraviolett-Laser entwickelt. Im Vergleich zu Infrarot-Lasermarkierungsgeräten verwendet die Maschine eine Intracavity-Frequenzverdopplungstechnologie dritter Ordnung, und der 355-Ultraviolettlicht-Fokussierfleck ist extrem klein. , kann die mechanische Verformung des Materials stark reduzieren und der Verarbeitungswärmeeffekt ist gering, da es hauptsächlich für ultrafeine Markierungen und Gravuren verwendet wird, besonders geeignet für die Lasermarkierung von Lebensmitteln, pharmazeutischen Verpackungsmaterialien, Mikrolöchern und hoch- Speed-Glasmaterialien. Trennen und komplexes Musterschneiden von Siliziumwafern und andere Anwendungsbereiche.

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.
