Abstract
An optical device has an LOE formed from a light-transmitting material having a first refractive index. A pair of parallel major external surfaces of the LOE guide image illumination within the LOE by TIR. At least one optical coupling configuration of the LOE deflects a proportion of the image illumination that is guided within the LOE by TIR. An optical material includes at least one transparent material directly attached to the LOE at least at the major external surfaces so as to be in direct contact with the major external surfaces and so as to at least partially encapsulate the LOE. The optical material has a second refractive index less than the first refractive index to maintain conditions of TIR at the major external surfaces. In certain embodiments, the TIR-guided image illumination is incident to the major external surfaces at angles greater than a critical angle, including shallow angles.
