  • Alignment material for liquid crystal lens and liquid crystal lens system
    Patent number: 9513510
    Abstract: There is provided an alignment material for a liquid crystal (LC) lens comprising a co-polymer of a photosensitive monomer and at least one alkyl methacrylate monomer. The material allows for the fabrication of a LC lens or LC lens system that is self-aligned and polarization-independent.

  • Apparatus light pen and its use
    Patent number: 9476569
    Abstract: A light pen for writing on a polarized light sensitive surface is disclosed. Light emitting diodes emit non-polarized light and a polarization block comprising of a truncated cone shaped collimating optical element, a broad band polarization divider, a broadband semi-wave plate, shifting bi-prism and light beam coupler are built to convert the non-polarized light to be converted to polarized uniform intensity light that is focused using a set of projection lens to a writing surface. The said light pen can be used for creating non erasable writing on many types of articles, documents, and records that would provide verification of authenticity and security.
