Abstract

Fluorine laser micro-structuring enables the generation of micro-optics in glasses and other wide band gap materials. For the generation of micro-lenses, we developed a new micro-structuring method and the appropriate hardware. The process is based on the mask projection technique and uses a set of different circular masks, which are placed consecutively within the laser beam. This creates a ring-shaped ablation area with variable inner radius. By using an appropriate set of masks, it is possible to generate a surface with a defined spherical shape. The measured radii of curvature of the structured micro-lenses are in the range of 90 μm up to 250 μm with corresponding surface roughness values to below 100 nm. The entire process and requirements are described, and the results are presented.
