Abstract

Disclosed is a spectral splitter device for transforming at least one initial light beam coming from a light source into more than two light beams, or vice versa, which includes: a first polarising beam splitter that splits the initial light beam into two orthogonally polarised beams; two optical elements respectively penetrated by the two orthogonally polarised beams; and a second polarising beam splitter and a third polarising beam splitter which split the two orthogonally polarised light beams into four respective output beams. Each of the two optical elements is birefringent and their birefringence depends on wavelength.
