ABSTRACT:
An optical element for a motor vehicle windshield comprises, in combination, an interference filter having one or more light-reflecting metal layers and one or more reflection-suppressing layers for coacting with the one or more metal layers to minimize reflection and enhance transmission in the visible region, a gradient band continuation of the interference filter above the direct line of forward vision through a windshield when disposed in a motor vehicle for reflective rejection of solar energy, such band including a light-reflecting metal layer gradually increasing in thickness toward a lateral edge of the band and an anti-glare backing behind the gradient band for suppressing luminous reflection from within the motor vehicle when the optical element is disposed in the windshield.
