Description:

The optical properties of a new photoalignment material RN-4942 and its applications for fabricating passive liquid crystal devices, including Pancharatnam-Berry phase optical elements and polarization volume holograms for AR/VR systems, are investigated. Compared to azo dye-based photoalignment materials, RN-4942 offers a much higher UV sensitivity, a faster fabrication process, and more resistance to mechanical vibrations and humidity during the fabrication process.
