RFH 355nm nano -seconds ultraviolet solid laser without trace marking mobile phone case   Laser marking mobile phone composite board, still need to see RFH high -power ultraviolet laser   The mobile phone composite board is made of a variety of materials such as PC, PMMA, UV transfer texture layer. Its non -metallic rear cover has become standard in the 5G era. Skills are continuously improved. Playing on the mobile phone composite board has also become a problem of many manufacturers. The smooth shell, the hard strength and the composite materials are obviously that the ink injection mark cannot be achieved.

  3w 5w  Pulsed UV Solid State Laser marking mobile phone case To meet the market demand, RFH newly developed S9 series UV laser in 2020. Comparing with its kinds, S9 series UV laser features with rugged sealed cavity, extremely compact size, simple and robust, high stability, high efficiency, high reliability and excellent laser beam quality.Its compact design suggests no necessity in building big light path, which greatly reduces space and cost and makes it easy to be installed into UV laser marking machines. In addition, S9 series cavity structure is more stability and more excellent scalability, which means the same laser cavity can be produces multi-power lasers , and the stability of different power ranges is greatly improved
