A beamsplitter device for splitting an input beam of light having a plurality of components into a corresponding plurality of output light beams that each travel in a substantially parallel manner. In one embodiment, the beamsplitter device is configured as a polarizing beamsplitter device so as to split the input beam into separate polarization components by using a polarizing coating. Alternatively, in another embodiment, the beamsplitter device is configured as a wavelength filtering beamsplitter so as to split the input beam into separate wavelength components, by using a plurality of wavelength division multiplexing (WDM) coatings. The beamsplitter device comprises a planar transparent structural sheet or wall having substantially parallel first and second opposing surfaces. An input face portion receives the input beam and a plurality of output face portions transmit the output beams. A reflecting material internally reflects light within the sheet. |
