ABSTRACT:
A spectral light division and recombination configuration and method has an incident face for light to be divided and at least one emergent face for recombined light. A spectrally selective light division system selectively separates light of a first spectral range from light of a second and of a third spectral range left combined. A recombining system recombining light of the first spectral range with light of the second and third spectral ranges are also included and the first spectral range is green light and is spectrally located between the second and the third spectral ranges.
