High efficiency Fresnel lens design and fabrication in a two-stage photopolymer

We show the design and fabrication of high diffraction efficiency, optically recorded gradient-index Fresnel lenses in a two-stage photopolymer. A design analysis reveals that lens f/# is limited by the material refractive index contrast, motivating use of recent high-contrast polymers. The number o...
