100‐2: Highly Transparent Photoalignment Material for Fabricating Holographic Optical Elements
SID Symposium Digest of Technical Papers2025Vol. 56(1), pp. 1386–1389
Abstract
The optical properties of a new photoalignment material RN‐4942 and its applications in fabricating passive liquid crystal devices, including Pancharatnam‐Berry phase optical elements and polarization volume holograms for AR/VR systems are investigated. Compared to conventional azo‐dye alignment materials, RN‐4942 offers a ~1000x higher exposure sensitivity, a faster fabrication process, lower dosage requirements, and greater humidity resistance during the fabrication process.
