355nm Ultraviolet (UV) Laser Modules, as a cold processing tool, can easily handle the processing of fragile materials such as curved glass and crystal. It has narrow pulse width and concentrated energy, which can directly destroy the chemical bonds of substances without heating, and is convenient and quick to operate, and is environmentally friendly. Therefore, it is an ideal tool for processing fragile materials. It can be used for marking, etching, engraving, etc. on the glass, and its application is very popular and extensive. Through computer operation and control, it can be precisely processed according to the design, and the pattern can be from millimeter to micron, so the anti-counterfeiting is good, the pattern is clear, neat and beautiful, and the traditional process cannot be compared with it.
