Optical coatings for glass and glass laminates

An optical coating for a substantially transparent substrate, comprising:

• an inner metal or metal alloy layer comprising a refractive index of about 4 or less, as measured at a wavelength of 550 nm, the inner metal or metal alloy layer comprising a first surface and a second surface, wherein the inner metal or metal alloy layer comprises an aluminum-silicon alloy;
• a first pair of transparent conductive oxide or dielectric layers, wherein each of the first pair of transparent conductive oxide or dielectric layers individually comprises a refractive index of about 3.0 or less, as measured at a wavelength of 550 nm, and wherein one of the first pair of transparent conductive oxide or dielectric layers is disposed over the first surface and the other of the first pair of transparent conductive oxide or dielectric layers is disposed over the second surface, wherein the first pair of transparent conductive oxide or dielectric layers comprises indium doped tin oxide;
• and
• a pair of outer metal or metal alloy layers disposed over each of the first pair of transparent conductive oxide or dielectric layers, wherein each of the pair of outer metal or metal alloy layers individually comprises a refractive index of at least about 2, as measured at a wavelength of 550 nm, wherein the pair of outer metal or metal alloy layers comprises a molybdenum-rhenium alloy;
• wherein the optical coating comprises an eye-weighted transmittance of less than about 20% and an eye-weighted reflectance of less than about 30%, as measured with a D65 illuminant according to the CIE 10° Standard Observer.
