A device suitable for manufacturing an optical registration carrier, such as a master plate, which device comprises a support for said optical registration carrier, at least a first and a second light source, wherein the wavelengths of the light from said first and said second light source are different from each other, as well as an objective disposed between said light sources and said support, which is movable with respect to said light sources. A correction lens is disposed between the first light source and the objective, which correction lens can be moved jointly with the objective. The focal points of the two light sources at least substantially coincide with various movements of the objective and the correction lens with respect to the light source.
