NON-CONVENTIONAL REFRACTIVE MICROOPTICS (NOCOREMO)

Abstract (Deutsch)

The project aims on improving the performance of refractive micro-optical elements by advanced design and fabrication to obtain highly innovative components. This will be done by reshaping of surfaces produced by reflow techniques. Two particular problems will be searched. The partners propose to investigate novel concepts and technologies suitable a) to shape and influence the microlens focus pattern (apodization, hybrid microlenses), b) to manufacture high-quality concave microlenses and microlens arrays. Focusing properties will be tailored by adding different filter functions to reshape the propagating light. This has a large potential in photolithography and for non-imaging applications in bio-medical research. Manufacturing of concave microlenses with excellent surface profiles and very low surface roughness is not possible with today's Microtechnology. Within this project concave microlens arrays will be fabricated and studied for beam shaping and as diffusers.
