ABSTRACT:
A light transmitting, absorbing coating is produced on a substrate by depositing layers of silicon in an oxidizing residual gas atmosphere and chrome in a non-oxidizing residual gas atmosphere in alternate layers cathode sputtering. The light transmitting layer comprises a substrate having a coating of a bluish-grey transmission color which comprises a plurality of alternate chrome and silicon dioxide layers with the thickness of the individual chrome layers being smaller than 10 nm.
