Whether you think about a table top system or a compact stand alone system, PHOTON ENERGY´s solutions are made for customers who are looking for a complete and ready-to-use laser marking system. The machines stand out due to their flexibility as well as their intuitive handling. Our marking systems can either be used as stand-alone-device or be integrated into automation solutions.
A saturated black color of the metallic surface can be achieved by using the CEPHEUS ultrashort pulse laser with our proprietary PERMAblack marking process. The markings created with this laser have a deep black appearance that is independent of the viewing angle (in contrast to annealing colors).
APPLICATIONS IN MEDICAL TECHNOLOGY
If corrosion-resistant parts are marked in black with the CEPHEUS laser, no subsequent passivation (protection against corrosion) of the marked surface is necessary, in contrast to marking with a nanosecond laser.
One particularly interesting application is the dark or black marking of anodized aluminum. In this case, no changes to the surface structure are identifiable even when the surface is examined under an electron microscope. Despite that, the marking is deeply black, independent of the viewing angle and completely abrasion-proof.
