METHOD FOR DETERMINING A BASE SYSTEM OF DIFFRACTION GRATINGS FOR COLOR 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.
