Abstract
A computer-implemented method and a device for optimizing an optical element comprising at least one diffraction grating, wherein at least one refractive surface contributing to the refractive light deflection and/or the at least one diffraction grating of the optical element are/is optimized in such a way as to minimize the color fringe and at least a second-order aberration of the optical element. Also, a corresponding production method and a corresponding device for producing an optical element comprising at least one diffraction grating.
