Written by leading researchers in non-imaging optics for illumination and solar concentrators, this is a hands-on tutorial for designing illumination optics to achieve higher efficiency, better miniaturization, and more distribution. As such, it includes design optimization, color mixing, CAD, and tolerancing, thus providing a solid framework for theoreticians and practitioners, as well as serving as a useful reference for lecturers in the field and students who plan to specialize in this area of optics. With a comprehensive glossary.
