title: Panorama of dual-mirror aplanats for maximum concentration.
abstract: Aplanats were recently analyzed for the first time as maximum-performance light-transfer systems with radiative transfer approaching the thermodynamic limit. We present a fundamental categorization scheme that appears to subsume the full spectrum of aplanatic designs, illustrated for far-field dual-mirror concentrators and motivated by high-irradiance solar applications.
