UV laser marking machine belong to the semiconductor laser marking machine in one, it can be described as the leader in laser marking machine.
Through special technology, the laser wavelength of UV laser marking machine is 355nm. Everyone in the industry knows that the wave of CO2 laser marking machine is 1064nm, the laser wavelength of the side-end pump semiconductor laser marking machine is 808nm, the fiber laser marking machine laser The wavelength is between 900-945nm. The shorter the wavelength, the higher the accuracy, the smaller the spot and the smaller the thermal influence!
Take a look at the difference between different laser marking machine on the marking principle of the processing object, the longer wavelength CO2 laser marking machine, side-end pump semi-laser marking machine, fiber laser marking machine produces the physical vaporization effect Or etching effect, and UV laser marking machine is indeed a chemical reaction in the photochemical reaction
From the above, we gradually understand that the vaporization effect can only be operated on the surface of the object, and the chemical light reaction directly cuts off the molecular chain of the article, so that we can understand that the UV marking machine can mark the information inside the transparent article Go, this is what we often say the internal laser marking.
Now we deeply understand that the new light source machine, UV laser marking machine is indeed the most high-end laser marking machine in the market. The accuracy and marking speed are several times or even hundreds times higher than that of other laser marking machines.
