Abstract:
An optical system including at least a first lens, a partial reflector and a reflective polarizer is described. The optical system has an optical axis such that a light ray propagating along the optical axis passes through the first lens the partial reflector and the reflective polarizer without being substantially refracted. At least one major surface of the optical system is rotationally asymmetric about the optical axis. A major surface of the optical system may have a first portion defined by a first equation and a second portion adjacent the first portion defined by a different equation. The first lens may have a contoured edge adapted to be placed adjacent an eye of a viewer and substantially conform to the viewer's face.

Claim (Index 26):
An optical system comprising:\n a first lens; a second lens, at least one of the first and second lenses having optical power in two mutually orthogonal directions; a partial reflector having an average optical reflectance of at least 30% for at least one desired wavelength; and a reflective polarizer substantially transmitting light having a first polarization state and substantially reflecting light having an orthogonal second polarization state, the optical system having an optical axis, a light ray propagating along the optical axis passing through the first lens, the second lens, the partial reflector and the reflective polarizer without being substantially refracted, wherein the optical system is rotationally symmetric about the optical axis with respect to light rays incident on the optical system and making a smaller first, but not a greater second, incident angle with the optical axis and wherein for each of the first and second incident angles, a plurality of incident light rays pass through the first lens, the second lens, the partial reflector and the reflective polarizer.
