| Abstract | We introduce a new method to obtain gradient index (GRIN) lenses by dual-step process based on interdiffusion of two different polymeric solutions and gelation of the final mixture. The aim of the study was investigated as a simple process to produce a gel characterized by a continuous axial concentration gradient starting from two thermoplastic polymers [poly(vinyl alcohol) and poly(acrylic acid)] having different refractive indexes. We also introduced a laser scanning system that is conveniently implemented to analyze the refractive index variation in the samples. © 2021 Optical Society of America |
