Abstract
The authors present high‐heat‐resistant inorganic optical elements with nano/micro structures for high power applications such as high‐lumen projectors. The nano/micro structures were fabricated by a high‐productivity sol‐gel based imprinting process. We sought to determine the optimal conditions for preparing the precursor sol for use in a sol‐gel based imprinting process. As a proof of concept, we used the technology to create form‐birefringent wave plates, micro lens arrays and holographic diffusers.
