20230174864 · 2023-06-08 ·

The present invention relates to polymer stabilized nematic liquid crystal microlenses. The microlenses can be made from a nematic liquid crystal, a chiral dopant, a reactive monomer, and a photoinitiator. The microlenses can be prepared by spin coating a liquid crystal mixture onto an array including a nickel transmission electron microscope grid. The focal length of the microlens array can be tuned electrically.
