EYEGLASS LENS HAVING A PLURALITY OF DIFFRACTION STRUCTURES FOR LIGHT
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.
