Modeling Diffractive Lenses Recording in Environmentally Friendly Photopolymer

The improvements made in diffusion models simulating phase image recording in photopolymers enable the optimization of a wide range of complex diffractive optical elements (DOEs), while the miniaturization of spatial light modulators makes it possible to generate both symmetric and non-symmetric DOEs. In addition, there is increasing interest in the design of new friendly recording materials. In this respect, photopolymers are a promising material due to their optical properties. In this paper, we show a procedure to record diffractive spherical lenses using a nontoxic optimized photopolymer. To achieve this goal, we followed three steps: first, the chemical optimization for DOE recording; second, the recording material characterization to be simulated by a three-dimensional diffusion model; and third, the evaluation of the coverplating for the conservation of the DOE.Work supported by “Ministerio de Economía, Industria y Competitividad” (Spain) (FIS2014-56100-C2-1-P and FIS2015-66570-P) and by “Generalitat Valenciana” (Spain) (PROMETEO II/2015/015)
