Abstract
An optical assembly includes at least one substrate that provides a first curved surface and a second surface. The optical assembly also includes a beam splitter on the first curved surface, a reflector on the second surface, and an optical retarder disposed between the beam splitter and the reflector. The optical assembly is configured to transmit the first light through the optical assembly at a first optical power. The optical assembly is also configured to transmit second light through peripheral portions of the optical assembly at a second optical power that is less than the first optical power. The first light includes light having a first polarization and wavelengths within a predetermined wavelength range. The second light includes light having wavelengths within the predetermined wavelength range and a second polarization orthogonal to the first polarization, as well as light having wavelengths outside the predetermined wavelength range.
