Abstract (en)
[origin: WO2013167824A1] The invention concerns an emission device (1) for emitting a light beam of controlled spectrum. The emission device comprises: - at least two separate light sources (Si to N) each emitting a light beam of wavelength lambdaiota or lambda2, and - spectral multiplexing means (25). The spectral multiplexing means (25) comprise an optical assembly (25) formed from at least one lens (25) and/or an optical prism. The optical assembly (25) has chromatic dispersion properties and moves the light beams spatially closer together. Moreover, each light beam having at least wavelength lambdaiota or lambda2 propagates in free space from the corresponding light source (Si to N) to the optical assembly (25). Therefore the emission device (1) is particularly robust. It can have small dimensions and be produced at low cost.
