| Zusammenfassung: | A device (10) for modifying electromagnetic illumination of a reflector aperture (12) defined by a reflector surface (R) is mounted in front of the reflector aperture (12) in a spaced apart relationship relative to the reflector surface (R). The device (10) at least partially covers the reflector aperture (12) and provides an illumination control means (20) for at least partially and selectively modifying electromagnetic illumination of the reflector aperture (12). The device (10) may include a membrane-like substrate (14) that is substantially transparent to electromagnetic radiation. A supporting member may support the substrate in the spaced apart relationship relative to the reflector surface (R). |
