Abstract: In some implementations, a diffusive optical device includes a glass substrate; a first polymer layer disposed on a first surface of the glass substrate; and a second polymer layer disposed on the first polymer layer. A refractive index of the first polymer layer may be different than a refractive index of the second polymer layer. The first surface of the glass substrate may comprise a central region and a margin region, wherein the first polymer layer is disposed on the central region and not the margin region. The first polymer layer may include a plurality of adhesion promoter molecules that causes the second polymer layer to bond to the glass substrate, wherein at least one adhesion promoter molecule, of the plurality of adhesion promoter molecules, comprises a molecularly flexible spacer.
