Abstract: Provided herein are devices and associated methods for the direction of light, e.g. sunlight. The devices may comprise various stacked optical elements, including wedge prisms and angled-facet minors, such as Fresnel prisms and mirrors. These may be rotated to effect various angles of light redirection. In one embodiment, the invention comprises directional reflectors which enable incident light to be reflected to a target of fixed location. In one embodiment, the target of the directional reflector is a solar energy target such as a thermal solar receiver or photovoltaic element. In another embodiment, the invention comprises directional beam guides which can redirect incident light arriving at a range of angles to a target. In one embodiment the target of the directional beam guide is the interior of a building, wherein directional beam guides are mounted in or on a window to effect light transmission to the target within the building.
