The invention reflection of incident electromagnetic radiation having an operating wavelength within the EUV range will not only reflective optical elements of the optical system for EUV lithography, a method for producing a reflective optical element of the optical system for EUV lithography, the reflective optical element 20 a multi-layer system, comprising a multi-layer system having a wave reflection phase (φ) (23, 83) and, a capping layer (25, 85) made from a capping material, and steps of the methods for: the cap for the capping layer material, this method comprising accordance phase of the reflected waves determining the dependency which changes according to the thickness of the capping layer, the phase of the reflected wave change substantially linearly with the thickness of the capping layer (25, 85) determining a linear region of the dependencies, and the thickness profile in the capping layer (25, 85) so that both of the maximum thickness and the minimum thickness of the thickness profile in the linear region To include the step of generating.
