Tailored imaging optics for concentration and illumination at the thermodynamic limit Conference Paper uri icon

abstract

  • Purely imaging strategies can offer ultra-compact concentrators and illuminators both of which approach the thermodynamic limit to optical performance. The tailored optical surfaces are monotonic functions that can be expressed analytically, which can facilitate optimization studies as well as practical fabrication. Also referred to as aplanatic designs, devices with two smoothly contoured surfaces can compete with, and even exceed, the performance of high-flux nonimaging systems. We develop and analyze tailored imagin devices for two-stage reflector systems of varying numerical aperture, motivated by applications in solar concentration as well as light collimation.
