Description

Direct Laser Interference Patterning

In Direct Laser Interference Patterning (DLIP), a substrate is irradiated with two or more coherent sub-beams, leading to a specific periodic modulation of the laser intensity distribution in the volume of beam intersection. This modulation can be directly transferred to the material surface by selective local ablation.

DLIP-treatment of cylindrical tools

In order to make function-optimised surfaces affordable for a wide range of applications, economic aspects such as throughput must be taken into account. Particularly, high production rates are enabled in Roll-to-Roll manufacturing. Therefore, the DLIP-machining of tools for Roll-to-Roll processes has been developed.
