Latest Patents

Leaman's latest patent is the Mesogen Polarizer, which relates to a polarization filter for ophthalmic lenses. This invention comprises a mesogen layer coated onto a retardation film, either directly or through an adhesive layer. The polarization filter is designed to employ a thin film or sheet that has a defined level of retardation between the light source and the mesogen layer. For instance, a cholesteric mesogen layer is utilized, allowing the multilayered laminate structure to demonstrate linear polarization of the light transmitted through it. This innovation can be applied in spectacle or eyeglass lenses, enhancing their performance by allowing transmission closer to the theoretical maximum.
