Master for the generation of microchannels for fluidic applications

Laser microprocessing with its numerous possibilities is applied in many fields.  The applications range from direct laser cutting with high precision of very diverse materials via micro mating of different combinations of materials, like ceramic membranes involving polymers as support material, through to surface modification by laser radiation. The application of ultra-short pulse laser systems enable a highly precise processing of transparent materials at minimum thermal interference.

Laser micro cutting

  • micro cutting of coated membranes
  • micro cutting of Teflon masters for printing technology and microfluidic applications
  • micro cutting of PDMS for the production of micro fluidics for Lab-on-a-Chip-systems

Laser micro drilling

  • micro drilling of apartures of adapted optical applications, microscopy
  • drilling of nozzle configurations
  • drilling of hydrogels for biology

Laser micro graving

  • laser micro labeling of components
  • surface structuring, e.g. tribology optimizing, polishing, roughening, production of cell guide structures

Laser functionalization

  • production of functional groups by laser radiation at reactive gas atmosphere
