ABSTRACT:
Field widening lens methods and systems are provided. The field widening lens includes a non-planar primary mirror and a secondary mirror. In addition, separate input and output ports are provided. The field widening lens further provides for an optical path difference for rays within the lens that is essentially zero for any ray within the field of view of an optical system including the field widening lens, regardless of the angle at which the ray entered the lens.
