Abstract

A beam directing device includes a transmissive element having an entry surface disposed in a first plane and an exit surface disposed in a second plane, the first and second planes intersecting to form a wedge angle. A first coating on the entry surface transmits a predetermined spectrum of light incident upon the first coating from external to the transmissive element at a normal angle of incidence and reflects the predetermined spectrum of light incident on the first coating from within the transmissive element at two times the wedge angle. A second coating on the exit surface reflects the predetermined spectrum of light incident on the second coating from within the transmissive element at the wedge angle and transmits the predetermined spectrum of light incident on the second coating from within the transmissive element at three times the wedge angle.
