Purple light UV laser marking machine takes 355nm pumped purple light laser device as the light source and takes advantage of previous generations machine to gain smaller diameter of focusing spot and fine marking effect. The metal absorb purple light higher than infrared and therefore more suitable for marking on metal and glass materials compared with infrared pump machine. Narrower pulse width of laser makes a shorter time of processing on materials, thus the materials avoid being deformed or burnt due to thermal. With smaller heat affected area and more beautiful marking effect, our products can meet customer’s demand of higher marking requirements.
