Abstract
Two reflecting surfaces (102, 104) pass through each other at an intersection line (450) lying in a plane of symmetry (106). The two surfaces share a common aperture (101) and the surface contours of the two surfaces are preferably mirror images of each other and are arranged such that the respective two foci (110, 120) of the two surfaces are equidistant (108) from the center of the shared aperture and offset from each other in equal and opposite directions (109a, 109b) from the plane of symmetry.
