Since frictional interactions in microscopically small components are becoming increasingly important for the development of new products for all modern technology, we present a laser-based technique for micro-patterning surfaces of materials using low-cost microlens arrays. By combining a laser direct-write technique on soda-lime glass and a thermal treatment, it was possible to obtain high quality microlens array elements using a low cost infrared laser widely implemented in industry which makes this technique attractive in comparison with other more expensive methods. The main advantage of using microlens arrays for micropatterning surfaces is the possibility of fabricating a large number of identical structures simultaneously, leading to a highly efficient process. In order to study the capabilities of the microlenses fabricated for microstructuring materials, identical structures and arrays of holes were fabricated over a variety of materials, such as stainless steel, polymer, and ceramic. The minimum diameter of the individual microstructure generated at surface was 5 mu m. Different nanosecond lasers operating at infrared and green wavelengths were used. The topography and morphology of the elements obtained were determined using confocal microscopy. (C) 2012 Society of Photo-Optical Instrumentation Engineers (SPIE). [DOI: 10.1117/1.JMM.11.2.023014]
