    "body_text": "Conventional lenses see an emitter from only one direction. Allight instead surrounds the source with a sequence of refractive interfaces designed to collect emission across the full 4-pi solid angle and adiabatically form a collimated output. The researchers experimentally demonstrate the underlying omnidirectional ray bending in two dimensions. The proposed device is broadband and non-resonant, but the paper's perfect-collector ambition extends beyond the dimensional demonstration reported here.",
