The invention relates to an optical system (60) comprising a dichroic plate (61) which is arranged to receive an incident light beam (90) and configured, firstly, to allow a portion of the incident light beam having wavelengths in a first range in the infrared range, referred to as the infrared light beam (92), to pass through it and secondly, to reflect another portion of the incident light beam having wavelengths in a second range different from the first range, referred to as the blue light beam (91). The optical system comprises a first lens (62) arranged to receive the infrared light beam and configured to shape the latter, a luminophore (64) arranged to receive the blue light beam and configured to convert it into white light, and a second lens (63) arranged to receive the white light with a view to forming a lighting beam (93).
