Abstract
A process is provided for producing a planar glass substrate coated with a dielectric layer system in which the individual layers are formed by a chemical vapor deposition coating process. After the layers have been applied, the glass substrate is either drawn, compressed, or its surface enlarged until the coating layers are reduced in thickness. A planar glass substrate having a multiplicity of extremely thin dielectric layers can be fabricated according to this process.
