The laser marking machine can mark various patterns through the laser, and what does the fineness of the marked line depend on? How to make the product mark more fine lines? TASTELASER, as a professional manufacturer of the laser marking machine, will explore and discuss the issues related to line fineness and the configurations of laser marking machine.
Firstly, the divergence angle of the laser beam from the laser marking machine should be considered, which is the fundamental immanent cause found from the principle of optics, the divergence angle of the laser beam means that all of the beams are propagated divergently, however, the divergence angle can measure the size of the divergence. A zero divergence angle is our ultimate goal in the laser industry. However, we can only make the laser divergence angle become close to zero theoretically and practically, but there is no way to achieve zero divergence angle. If beam of parallel light passes through the focus lens, the parallel light will converged at one point, which is a straight, positive and infinitely small point. But because there is no true parallel light with a divergence angle of zero in the world, it is impossible to achieve an infinitely small point. The size of the focused points varies, and this size is just proportional to the line marked with our marking machine. The beam expander is an optical element that we use to compress the divergence angle of the laser beam, and when the multiples of the beam expander are enlarged, the divergence angle of the laser beam will become smaller.
Secondly, the performance of the laser itself of the laser marking machine should be considered, the laser with a good laser beam will have a small divergence angle, and the laser with a poor laser beam will have a large divergence angle, it is why no beam expander is used in the fiber laser marking machine, however, the semiconductor marking machine is used. Of course, the quality of the laser becomes very important when our customers choose a laser marking machine.
Thirdly, the factors to be considered include the interaction between the laser energy of the laser marking machine and the matter. It means that the laser marking machines in the same model can mark different matters and the fineness of the lines will also be different, if the used laser energies are different, then the fineness effects of the marked lines will also be different.
The laser marking machine produced by TASTELASER can be configured with different lasers to meet the marking adjustment according to the different needs of customers. If you have any questions, please contact our staff promptly.
