  Gradient index optical materials are formed by drop by drop dispensing of nanoparticle/monomer suspensions. Refractive index variations are defined by nanoparticle concentrations that can vary in three dimensions. Droplets of differing compositions can be mixed, and droplets or layers or droplets are partially cross-linked by exposure to ultraviolet radiation prior to dispensing additional droplets. Gradient index optical elements such as lenses, prisms, and waveguides can be formed in flexible polymer layers.

  渐变折射率光学材料是通过滴滴分配纳米颗粒/单体悬浮液形成的。折射率变化由纳米颗粒浓度在三个维度上变化定义。不同成分的液滴可以混合，液滴或液滴层可以在分配额外液滴之前通过紫外线辐射部分交联。可以在柔性聚合物层中形成渐变折射率光学元件，如透镜、棱镜和波导。
