Replication, characterization and simulation of micro injection molded microlens arrays using technical amorphous polymers
Novel results relating to the characterization of microlens array production by simulation and micro injection molding were examined to produce precise micro-optics from Polymethylmethacrylate (PMMA),Polycarbonate (PC) as well as Polystyrene (PS).The microlens arrays show 100 lenses in a 10×10 array with a lens radius of 271 μm and a lens depth of 45 μm.The pitches between the lenses are fixed at 800 μm.The surface of the ultra-precision diamond end-ball milled microlens array mold was polished to reduce the surface roughness of the injection molded specimen.The injection molding parameters were optimized to get precise lens geometries with high shrinkage uniformity by simulation and experimental methods.The injection molding results show precise injection molded microlens arrays and PC microlens array shows the best geometrical results compared to the microstructured insert.
