Dark mirror optical stack and related systems
Abstract
A dark mirror optical stack, particularly a low emittance, high absorbance dark mirror optical stack is provided. The dark mirror optical stack includes a polyimide substrate containing carbon filler, an aluminum layer on the polyimide substrate, a first silicon oxide layer on the aluminum layer, a chromium layer on the first silicon oxide layer, and a second silicon oxide layer on the chromium layer. In a particularly exemplary embodiment, the aluminum layer has an average thickness of 600 to 2000 Angstroms, the first and second silicon oxide layers have average thicknesses of 500 to 1000 Angstroms, and the chromium layer has an average thickness of 40 to 100 Angstroms.
