Abstract

Collimating light is a common task in optical design. The smaller the source, the simpler the optics required for collimation. Small sources cannot emit sufficient power for some demanding applications. Larger sources are required. The physical limits of collimation due to the conservation of ´etendue and skewness are discussed. Two systems are presented:a domed nonimaging Fresnel lens with toroidal primary focus and our "Umbrella" optics consisting of two free-form non-aximsymmetric mirrors.
