Abstract
An optical element constructed from a transparent support having a curved surface and a layer of a polarization-dependent film that is affixed to the curved surface. The polarization-dependent film passes linearly polarized light of a predetermined polarization while reflecting linearly polarized light having a polarization orthogonal to the predetermined polarization. The element is constructed by applying a layer of a transparent adhesive either to the layer of polarization-dependent film or to the curved surface. The support and layer of polarization-dependent film are then heated to a temperature above the temperature at which the polarization film can be deformed. The support and layer of polarization-dependent film are then pressed together so as to deform the layer of polarization-dependent film to cause the layer of polarization-dependent film to conform to the curved surface.
