Air holes turn silicon wafers into flat ultraviolet focusing mirrors for compact optics
Researchers have found a way to create flat mirrors that focus ultraviolet light using silicon wafers with air holes. This innovation could enable compact, high-resolution imaging and sensing systems. The technology uses metasurfaces with nanoscale structures.
Why it's good news: It brings us closer to developing smaller and more efficient optical instruments that can be used in a variety of applications.
