METHOD FOR DETERMINING A BASE SYSTEM OF DIFFRACTION GRATINGS FOR COLOUR FRINGE CORRECTION OF SPECTACLE LENSES |
摘要 |
A method for producing a series of base lenses, which cover a predetermined power range, wherein each base lens of the series has a base power different from the base powers of the other base lenses of the series, and has at least one diffractive base grating, the method comprising: specifying the base powers of each base lens of the series and calculating the base grating of each base lens of the series so as to minimize the color fringe of the respective base lens with the specified base power in a predetermined region of the spectacle lens. |
