Abstract
Embodiments related to making an optic comprising a cladding are disclosed. One example embodiment comprises forming a wedge-shaped light guide having opposing first and second faces and comprising a material having a first refractive index. The embodiment further comprises applying a cladding layer to the first face, and, applying an interface layer to the cladding layer. In this embodiment, the cladding layer has a second refractive index less than the first refractive index, and the interface layer has a third refractive index matched to the first refractive index.
