Abstract: In some implementations, an optical element comprises a glass substrate, a dark mirror coating disposed on a first surface of the glass substrate, and a lens disposed on a second surface of the glass substrate. An aperture is formed in the dark mirror coating, and the aperture is aligned with the lens. The optical element is a monolithic optical element.

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.
