Three-dimensional gradient-index optics via injketaided additive manufacturing techniques

Abstract

The ability to correct for monochromatic aberrations without the need for complex geometry has made gradient-index optics an attractive area of research, but manufacturing challenges have limited their application to a select few areas. In this study, a novel method for fabricating gradient-index lenses using inkjet solid free form three-dimensional printed optical polymers is proposed. A flat gradient-index lens based on the fabrication constraints is optimized using a powerful customized design synthesis tool. Cross-sectional views of its continuous index profile and a representative binary pixel-map are shown.
