In this tutorial, we assume that you are familiar with basic geometrical (i.e., ray) optics, including Snell’s law of refraction, total internal reflection (TIR), first-order imaging optics, and spectra. We also assume that you have some experience in illumination optics. However, even if you are a novice, this tutorial will be useful for you, because it will show you a glimpse of many important design methods and elements with which you must get acquainted. If you are an experienced imaging optics designer, this tutorial will be useful for you, too, because illumination design requires a different way to think about light. We will mostly ignore diffraction, polarization and coherence; and will consider only homogeneous, isotropic, and linear (HIL) materials—i.e., we will mostly ignore gradient index materials, birefringence, and nonlinear optics. These aspects of physical optics are deep and fascinating, but we have so rarely encountered design tasks where they are important that we are limiting the scope of this tutorial to geometric optics and HIL materials. Although indeed important for illumination design, we will also not discuss color mixing and homogenization in detail: we refer the reader to our recently published tutorial1 on color mixing.
