ABSTRACT:
Embodiments of the present invention are directed to single prism beamsplitters and compound beamsplitters formed from combining one or more of the single prism beamsplitters. In one embodiment, the beamsplitters can be configured to produce one or more split beams of light that can emerge at angles other than 90° to one another. The prisms of the beamsplitter embodiments are configured so that light propagating through prisms encounter one or more intermediate planar surfaces at various angles with respect to the path of the light. A certain number of the intermediate planar surfaces can be angled so that the light transmitted along a particular path undergoes total internal reflection within the prism. A number of other intermediate planar surfaces are angled so that the light transmitted along a particular path does not undergo total internal reflection.
