The medical field uses high-contrast marking, sometimes called black marking, to mark medical tools. White-marking enhances the visible quality of watches and jewelry products.

Femtosecond lasers offer improved quality compared with ps and ns lasers and expand the number of materials on which it is possible to apply high contrast marking. It is possible to apply deep engraving, high contrast marking, medical instrument marking, hidden marking, counterfeit marking on glass, plastic, metals, and ceramics. Corrosion-free marking is possible on stainless steel.

Both PHAROS and CARBIDE lasers are the choice for high contrast versatile marking. BiBurst is an essential option for achieving high contrast markings.
