摘要： The invention is directed to a spectacle lens and includes a body which is transparent or at least partly transparent to light and has a phase object which guides the light incident at an angle of incidence α on a side facing away from an observer into a direction depending on the wavelength λ of the light and the angle of incidence α thereof. The phase object has a multiplicity of diffraction structures, which diffract monochromatic light at a wavelength of 380 nm≤λ≤800 nm with a diffraction efficiency of η≥70% into one and same order of diffraction |m|≥1 when the monochromatic light is incident at an angle of incidence α on the side of the lens facing away from the observer which lies within a diffraction-structure-specific angle interval 15° wide and dependent on the wavelength of the light.

摘要： An illumination apparatus includes a first solid-state-based illumination module, a second solid-state-based illumination module, and a superposition unit, which couples first and the second luminescence radiation into an illumination beam path, in which said radiation is guided up to the end of the illumination beam path in order to illuminate a light modulator. A filter unit which filters light with a second color from the first luminescence radiation with a first color and from the second luminescence radiation such that light with the first and second color is present at the end of the illumination beam path.

摘要： An illumination apparatus for a projector that includes a light modulator is provided. The illumination apparatus includes a first illumination module emitting first radiation, a second illumination module emitting second radiation, a light mixing rod extending in the axial direction and a superposition unit, which superposes the first and second radiation and couples this into the light mixing rod. The superposition unit includes a first imaging optical unit which focuses the first radiation into the light mixing rod such that a first focus is present, and a second imaging optical unit which focuses the second radiation into the light mixing rod such that a second focus is present. The first focus is spaced apart from the second focus in the axial direction.
