Abstract
A laminated window assembly has a first glass pane with a coating formed thereon, a second glass pane, and a polymeric interlayer provided between the first glass pane and the second glass pane. The coating includes a first layer deposited over a major surface of the glass pane, wherein the first layer has a refractive index of 1.6 or more and a thickness of 50 nm or less, a second layer deposited over the first layer, wherein the second layer has a refractive index that is less than the refractive index of the first layer and a thickness of 50 nm or less, a third layer deposited over the second layer, wherein the third layer has a refractive index that is greater than the refractive index of the second layer and a thickness of less than 500 nm, and a fourth layer deposited over the third layer, wherein the fourth layer has a refractive index that is less than the refractive index of the third layer and a thickness of 100 nm or less.
