Why are 3w5w UV laser marking machines equipped with RFH 355nm UV laser Nanosecond UV lasers have superior beam quality Solid-state UV laser has high marking accuracy   At present, most of the laser power of UV laser marking equipment on the market is 3W~5W. The marking machine of this power range is most used in plastics, circuit boards, silicon wafers, LCD liquid crystal glass, glassware, Metal surface coatings, electronic components, wood, jade and other materials have a wide range of mature applications.   Among them, the lasers of 3W～5W ultraviolet laser marking machines in many factories are equipped with RFH. There are many reasons for this.
