Abstract

Total internal reflection (TIR) prisms are commonly used as collector elements in the concentrating solar technical field. These prisms use the index change between glass and air to create an internal reflection of light. Because the index change is critical, it is necessary to keep optically active surfaces of the prisms in contact with air. Air has a refractive index of 1.0. Recently, coatings with a refractive index of near 1.0 have become available. These coatings could be used instead of air to create TIR in the prisms. This coating protects optically active surfaces from dust and at the same time allows them to be held in place with physical mechanisms.
