1. A hybrid optic comprising:a capillary optic for receiving x-rays from an x-ray source at an entrance portion of the capillary optic and configured to provide substantially parallel or substantially diverging x-rays at an exit portion of the capillary optic; anda grazing incidence multi-shell optic (GIMSO) coupled, at an entrance portion of the GIMSO, to the exit portion of the capillary optic to receive the substantially parallel or substantially diverging x-rays emerging from the exit portion of the capillary optic, the GIMSO comprising an exit portion for providing x-rays. 2. The hybrid optic of claim 1, wherein the capillary optic is configured to receive substantially diverging x-rays at the entrance portion and configured to provide substantially diverging x-rays at the exit portion of the capillary optic. 3. The hybrid optic of claim 2, wherein the GIMSO is directly coupled to the capillary optic and configured to receive the substantially diverging x-rays directly from the exit portion of the capillary optic and configured to provide substantially converging x-rays at the exit portion of the GIMSO. 4. The hybrid optic of claim 1, wherein the capillary optic is configured to receive substantially diverging x-rays at the entrance portion and configured to provide substantially parallel x-rays at the exit portion of the capillary optic. 5. The hybrid optic of claim 4, wherein the GIMSO is directly coupled to the capillary optic and configured to receive the substantially parallel x-rays directly from the exit portion of the capillary optic and to provide substantially converging x-rays at the exit portion of the GIMSO. 6. The hybrid optic of claim 1, wherein the acceptance angle of x-rays at the entrance portion of the capillary optic is greater than 3 degrees from a central axis of the capillary optic. 7. The hybrid optic of claim 1, wherein the acceptance angle of x-rays at the entrance portion of the capillary optic is greater than 6 degrees from a central axis of the capillary optic. 8. The hybrid optic of claim 1, wherein the capillary optic has a focal length less than or equal to 60 mm and the GIMSO has a focal distance greater than 100 mm. 9. The hybrid optic of claim 1, wherein the GIMSO comprises a single reflection optic. 10. The hybrid optic of claim 1, wherein the GIMSO comprises a double reflection optic. 11. The hybrid optic of claim 1, wherein the GIMSO comprises a cylindrical spiral geometry. 12. The hybrid optic of claim 1, wherein the GIMSO comprises a conical spiral geometry. 13. The hybrid optic of claim 1, wherein the GIMSO comprises a nested cylinder geometry. 14. The hybrid optic of claim 1, wherein the GIMSO comprises a metal coated foil capable of being shaped into a desired geometry. 15. The hybrid optic of claim 1, wherein the GIMSO comprises a machined metal surface rigidly manufactured into a desired geometry. 16. The hybrid optic of claim 14, wherein the metal comprises at least one of nickel, gold and iridium and the foil comprises at least one of a plastic foil, aluminum foil and quartz ribbon. 17. The hybrid optic of claim 10, wherein the GIMSO includes a first surface positioned to reflect x-rays provided by the capillary optic and a second surface to reflect x-rays reflected from the first surface. 18. The hybrid optic of claim 17, wherein the first surface includes a first parabolic surface and the second surface includes a second parabolic surface. 19. The hybrid optic of claim 17, wherein the first surface includes a parabolic surface and the second surface includes a hyperbolic surface. 20. The hybrid optic of claim 1, wherein the capillary optic comprises a bundle of glass capillary tubes.
