Abstract
An image assembly may include a substrate having a face, a first optical layer and at least one spacer member. The imaging assembly may also include an anti-reflection structure. The at least one spacer member may be arranged between the substrate and the first optical layer to define an air gap therebetween. The anti-reflection structure may be coupled to at least part of the face and at least one of the first optical layer and the at least one spacer member. The anti-reflection structure may also include a plurality of projections having dimensions smaller than a wavelength of radiation to be imaged by the imaging assembly.
