Nanosecond solid-state 355 uv laser source marks on glass with a size error of only 0.05mm   Good quality, made by RFH! The customer repurchased the 355 uv laser source engraved glass again     When the light beam enters the glass, some of the light is reflected off the surface, and most of the light is transmitted directly through the glass, and the same goes for UV rays. When the ultraviolet laser emits ultraviolet laser to the glass surface, it will be etched, so as to achieve the purpose of marking on the glass.
