laser surface structuring (DLIP)

In direct laser interference patterning (DLIP), a laser beam is split into several coherent partial beams and superimposed on the surface. The resulting interference pattern creates highly reproducible micro- to nanostructures in a single processing step – for example grooves, hexagonal dot arrays or 3D reliefs – with typical periods ranging from 300 nm to 30 µm.

DLIP can be applied to metals, polymers, glass and ceramics and is used to generate specific surface functionalities: for example lotus effect (hydrophobic), “moth-eye” (low reflection), anti-fog/anti-glare properties, as well as optically active structures for holograms and product protection. In our systems, DLIP can also be applied to components with demanding geometries – over large areas, at high speed and with reliable process stability, making it ideal for medical technology and precision engineering.
