Abstract

IR absorbing layers are used to transform radiation into heat. They must combine high absorption with low film thickness. Three methods for their deposition have been investigated: - Thin metallic films. - Platinum black deposited by a galvanic process. - Highly porous metals deposited by evaporation in nitrogen.
