Purple light UV laser marking machine takes 355nm pumped purple light laser device as the light source and take 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.

The UV laser is cold ligh source . UV laser with short wavelength , focus , smaller spot , belongs to cold process with a little heat affecting , good beam quality , it can achieve hyperfine marking . Most materials can absorb ultraviolet laser , it is widely applied on industrials ; with very little heat affecting area , it won't have heat effect , there is no burning problem , pollution-free , non-toxic , high marking speed , high efficiency , the machine performance is stable, low power consumption.
