One optical system comprises a first optical surface, a faceted second optical surface, and a faceted third optical surface. The optical system is operative to convert a first bundle of rays that is continuous in phase space outside the first optical surface into a second bundle of rays that is continuous in phase space outside the third optical surface. Between the second and third optical surfaces the rays making up the first and second bundles form discrete sub-bundles each passing from a facet of the second optical surface to a facet of the third optical surface. The sub-bundles do not form a continuous bundle in a phase space that has dimensions representing the position and angle at which rays cross a surface transverse to the bundle of rays. |

1. An optical system comprising, in order:
a first optical surface at which light is deflected only a predetermined number of times; a faceted second optical surface; and a faceted third optical surface; wherein the optical system is operative to convert a first bundle of rays that is continuous in phase space outside the first optical surface into a second bundle of rays that is continuous in phase space outside the third optical surface; wherein between the second and third optical surfaces the rays making up the first and second bundles form discrete sub-bundles each passing from an element of the second optical surface to an element of the third optical surface, and the sub-bundles do not form a continuous bundle in phase space; wherein the phase space has dimensions representing the position and angle at which rays cross a surface transverse to the bundle of rays.
