Long-wavelength infrared imaging makes it possible to see in complete darkness and through smoke and fog. However, they use bulky lenses that are expensive.Long-wavelength infrared imaging makes it possible to see in complete darkness and through smoke and fog. However, traditional systems leveraging LWIR use bulky refractive lenses. These heavy lenses are often crafted from expensive materials like germanium, hindering widespread adoption.
Scientists can control how light interacts with the surface by carefully arranging these nanopillars. This manipulation allows them to achieve results similar to traditional optical systems at just a fraction of their thickness. Led by Associate Professor Arka Majumdar, the team’s approach aims to address challenges associated with broadband meta-optics and demonstrateLeft: A full view of a fabricated wafer containing meta-optics.

These meta-optics contain both complex light scatterers and simple scatterers . model, to expedite the design process.
