Abstract
A lens having an axis of symmetry, including a transparent circumferential surface, circumferentially extending about the axis of symmetry, the transparent surface having optical power in planes which include the axis of symmetry, a first reflective surface, symmetric with respect to the axis of symmetry and being operative to reflect light passing through the transparent surface and a second reflective surface, symmetric with respect to the axis of symmetry and axially spaced from the transparent surface and being operative to reflect light reflected by the first reflective surface.
Claims46
A lens having an axis of symmetry, comprising:
- a transparent circumferential surface, circumferentially extending about said axis of symmetry, said transparent surface having optical power in planes which include said axis of symmetry;
- a first reflective surface, symmetric with respect to said axis of symmetry and being operative to reflect light passing through said transparent surface;
- and
- a second reflective surface, symmetric with respect to said axis of symmetry and axially spaced from said transparent surface and being operative to reflect light reflected by said first reflective surface.
