Microscopic Liquid Crystal Lens
August 11, 2015 | Terry Sharrer
Liquid crystals are often associated with electronic displays and cell membranes. But they are widely employed in developing optical devices and this piece describes liquid crystal lens fabrication that resembles a fly’s compound eye. Chemists at the University of Pennsylvania used ultraviolet light to etch pillars on polymer plates. They then applied a microscopic liquid crystal which self-assembled into compound lenses permitted polarized light alterations to give multiple depths of field. These images can then be reconstructed 3-D pictures. MORE
