Zusammenfassung:An apparatus for obtaining energy from a polychromatic energy source that emits radiation in a first and a second wavelength band comprises a reflector or an energy receiver having an aperture therein; and a holographic lens that diffracts and focuses the radiation within the first wavelength band from the energy source through said aperture towards a first energy receiver, and transmits the radiation within the second wavelength band from the energy source to the reflector or energy receiver. If a reflector is used, the reflector reflects the radiation transmitted by the holographic lens towards a second energy receiver.
