1. An optical device for partially reflecting a first set of light waves having a given polarization state and located within a given optical spectrum and within a first angular spectrum, and transmitting a second set of light waves having the same given polarization state and located within the same given optical spectrum and within a second angular spectrum, comprising:

  • a first light-transmitting substrate having a surface, anda dichroic coating disposed on said surface,characterized in that angles located within said first angular spectrum are smaller than angles located within said second angular spectrum and that the reflectivity by the coated surface of said first set of light waves is higher than the reflectivity by the coated surface of said second set of light waves.
