[Paper] Fabrication of High-Quality Adjustable Liquid-Crystal Lens Using Liquid-Crystalline Polymer

Abstract

We propose an adjustable-focus lens composed of a liquid crystal and a Fresnel lens fabricated from a liquid-crystalline polymer. Using vertically aligned liquid-crystalline polymers and fabricating Fresnel lenses by the imprinting method, we achieved uniform, vertically aligned liquid crystals on a Fresnel lens. The results demonstrate that a high-quality, adjustable-focus liquid-crystal lens that does not exhibit light scattering caused by the surface structure of the Fresnel lens can be realized.
