OPTICAL SUBSTRATE AND METHOD AND DEVICE FOR PRODUCING OPTICAL SUBSTRATES

摘要

The invention relates to an optical substrate on which at least one layer is to be arranged in such a way that the propagation of light is influenced. Th e aim of the invention is to reduce the production time for one such substrate and to preferably significantly reduce the surface strains thereof. To this end, the inventive substrate is produced by means of an application method which is characterised in that at least one of the layers applied comprises halogen atoms or a halogen compound.
