In case of transmitted light, the direction of the refracted and transmitted ray changes according to Snell’s law of refraction, according to which the sine of the angle between the incident ray and the normal is in constant ratio with the sine of the angle between the refracted ray and the normal, with all three being coplanar (Winston, Minano, & Benitez). Based on these universal laws of light, the behavior of a light ray in any optical system can be predicted. Simple optical systems can be predicted manually, but complex ones require sophisticated computer programs that can easily predict the behavior of light through computerized ray tracing. Even the analysis and design of solar concentrators requires such a program. Ray tracing is the process of constructing or following the paths of light rays through an optical system consisting of refracting and reflecting surfaces (Winston, Minano, & Benitez, 2005). For instance, the transmission of a specific concentrator can be determined through ray tracing as follows: N rays enter a concentrator’s aperture at a ? angle of incidence at the entry aperture of the concentrator, as shown in Figure 4.1. Fig. 4.1: Ray tracing of the rays transmitted through a concentrator to determine transmission (Winston, Minano, & Benitez, 2005). After the rays are traced through the optical system, N’ rays appear from the concentrator’s exit aperture. The dimensions of the exit aperture are determined based on the required concentration ratio of the system. The remaining N and N’ rays are lost through various processes such as ray scattering. The transmission power of the system for a different angle of incidence ? can then
