DURABLE LOW-EMISSIVITY SOLAR CONTROL THIN FILM COATING Abstract of the Disclosure An infrared reflecting interference filter capable of transmitting a desired proportion of visible radiation while reflecting a large portion of incident solar radiation is provided. The filter consists of a transparent substrate coated first with a dielectric layer, next a partially metal reflectance layer, and finally an outer protective dielectric layer. In addition, between each metal-dielectric interface is deposited a nucleation or glue layer that facilitates adhesions and improves chemical and mechanical resistance. The interference filters are durable and can be modified to provide a full range of optical and electrical characteristics. The dielectric layer can comprise of composite films consisting of silicon nitride in combination with zirconium nitride, titanium nitride, and/or hafnium nitride.
