China Uv Laser Marking Machine Product detail Features of 5w uv laser marking machine: 1. UV laser marking machine adopts 355nm pumped UV laser device, so as to get smaller diameter of focusing spot and fine marking effect. 2. The metal absorb UV higher than infrared and therefore more suitable for UV laser marker marking on metal and glass materials compared with infrared pump machine. 3. Superior laser beam and uniform power density, stable laser power. 4. With smaller heat affected area and more beautiful marking effect,http://www.prxcnc.com/laser-ma....rking-machine/uv-las
