Abstract
An optical separator device for splitting a beam of incident polychromatic light into a plurality of spacially and spectrally separated component beams having parallel optical axes including a first composite for spectrally and spacially separating the incident beam into a first plurality of component beams and having a first plurality of parallel, spectrally selective, reflective layers including a layer adapted to reflect light in a first spectral range and a second spectral range; a second composite for further spectrally and spacially separating the first plurality of component beams into a second plurality of component beams and having a second plurality of parallel, spectrally selective, reflective layers including a layer adapted to reflect light in the spectral range and to transmit light in the second spectral range.
