Claim 0:
1. An optical device, comprising:
a first polarization selective reflector; and
a second polarization selective reflector positioned relative to the first polarization selective reflector so that the first polarization selective reflector directs first light having a first polarization toward the second polarization selective reflector and the second polarization selective reflector directs second light having a second polarization toward the first polarization selective reflector, wherein:
a first plane defined by the first polarization selective reflector intersects a second plane defined by the second polarization selective reflector at a first angle; and
the first angle is measured between a portion of the first plane that directs the first light and a portion of the second plane that directs the second light.
