Abstract: The fabrication of microlens based on a novel photopolymerizable formulation, consisting of acrylated hyperbranched polyisophthalate (HPIPA), 1,6-hexanediol diacrylate (HDDA) and Irgacure 184, with the free flow technique was presented. The good focalization and low chromatism of the fabricated microlens were obtained with scanning near-field optical microscope and measuring the optical transfer function versus spatial frequency, respectively. The positive effects of good compatibility with acrylated monomers and a low shrinkage degree for HPIPA on focalization have also been described. The further research work about the fabrication of microlens with acrylated hyperbranched polyisophthalate is in progress.
