70‐3: Invited Paper: Polarisation Independent Liquid Crystal Lenses using Embossed Reactive Mesogens. Issue 1 (29th May 2019) - Jones, J. Cliff
Abstract : Liquid crystal lenses have promise in optical systems owing to their tunability combined with low electrical power, cost and weight. A good example of such a system is switchable contact lenses for the correction of age‐related presbyopia. Large phase modulation can be done using nematic liquid crystals. However, the birefringent materials are inherently polarisation dependent, usually requiring orthogonal polarisations to be focused separately. A novel method is presented for producing polarisation independent lenses based on reactive mesogens.
