Some embodiments provide an illumination optical system. The optical system can include a first surface and a second surface. Each of the first and second surfaces can further comprises a multiplicity of corresponding Cartesian-oval lenticulations such that each lenticulation of the first surface focuses a source upon a corresponding lenticulation of the second surface and each lenticulation of the second surface focuses a target upon a corresponding lenticulation of the first surface.

1. A rotation symmetric optical system receiving light from a source and sending it to a target, the system comprising: four optical surfaces, which are ordered by a light trip from the source towards the target,wherein the four optical surfaces comprise a first surface, a second surface, a third surface, and a fourth surface;wherein the second surface defines a change of material and refractive index and where two of the four surfaces have coordinated lenticulations forming a Kohler radial integrator such that one surface of the Kohler radial integrator images the source onto another surface of the Kohler radial integrator and the another surface of the Kohler radial integrator images said one surface onto the target. 2. The system of claim 1, wherein the two surfaces forming the Kohler integrator are the third and fourth surfaces where the third surface comprises a primary mirror and the fourth surface comprises a secondary mirror. 3. The system of claim 1, wherein the two surfaces forming the Kohler integrator are the third and fourth surfaces where the third surface comprises a primary mirror and the fourth surface comprises a refracting surface. 4. The system of claim 1, the first surface is a flat refractive surface, and the second surface, the third surface and the fourth surface are refractive surfaces; wherein the first flat refractive surface and the second, third and fourth refractive surfaces define changes of material and refractive index. 5. The system of claim 4, wherein the two surfaces forming the Kohler integrator are the second and the third refracting surfaces. 6. The system of claim 5, wherein the second refractive surface has Fresnel faceting. 7. The system of claim 1, wherein the fourth surface is a refractive dome above the target. 8.

The system of claim 8, wherein the two surfaces forming the Kohler integrator comprise the primary mirror surface and the secondary mirror surface, and where the second refractive, surface does not define a change of material and thus the material after the first surface is the same until the light reaches the dome forming a single solid piece. 10. The system of claim 8, wherein the two surfaces forming the Kohler integrator are the first and second refractive surfaces. 11. The system of claim 8, wherein the two surfaces forming the Kohler integrator are the first refractive surface and the primary mirror surface. 12. The system of claim 8, wherein the two surfaces forming the Kohler integrator are the first refractive surface and the secondary mirror surface. 13.

The system of claim 8, wherein the two surfaces forming the Kohler integrator are the second refractive surface and the secondary mirror surface. 22. The system of claim 8, wherein the two surfaces forming the Kohler integrator are the second refractive surface and the refractive dome. 23. The system of claim 8, wherein the two surfaces forming the Kohler integrator are the primary mirror surface and the refractive dome. 24. The system of claim 8, wherein the two surfaces forming the Kohler integrator are the secondary mirror and the refractive dome.
