The present invention relates to a novel process for the production of sequences of interference layers composed of layers i of prescribed thicknesses d(i) and refractive indices n(i). In this process a stack of at least two layers i of glasses having refractive indices n(i) and thicknesses d (i), which are each larger than the predetermined thicknesses d(i) by the same multiplying factor, is provided. The stack is heated to a temperature above the transformation temperature of the glasses and during or after heating, the stack is drawn in such a manner that the individual layers obtain the prescribed thicknesses d(i). After this the drawn stack is cooled.
