At MLL, a process for the production of so-called microcracks in transparent materials has been developed. In addition to the direct separation of the material, this also allows defined break edges to be generated.
By limiting the production of microcracks to the interior of a substrate, it is possible to produce durable, surface-neutral markings.
Exemplary applications are the introduction of 2D codes and orientation grids in slides.
It works with a combination of nanosecond laser, high-precision linear axes and galvanometer scanners, which allows complex structures to be realized in a short time.
