Microlens arrays made of glass are optical components which, due to their complexity, can fulfill the function of many larger lenses at the same time. Optical arrangements can thus be miniaturized and made lighter. The production of such elements can be a challenge, especially for medium and small quantities. Therefore, at the ifw Jena, two direct production methods of such elements are being investigated: laser ablation with ultrashort pulsed lasers and ablation with short pulsed CO₂ lasers, respectively polished with cw-CO₂-lasers. The experiments show a good homogeneity of the lenses as well as a high process speed.
