An optic device, system and method for making are described. The optic device includes a first solid phase layer having a first index of refraction with a first photon transmission property and a second solid phase layer having a second index of refraction with a second photon transmission property. The first and second layers are conformal to each other. The optic device may be fabricated by vapor depositing a first layer and then vapor depositing a second layer thereupon. The first layer may be deposited onto a blank or substrate. The blank or substrate may be rotated during deposition. Further, a computer-controlled shutter may be used to alter the deposition rate of material along an axis of the optic device. Alternatively, the optic device may be moved at varying speeds through a vapor stream to alter the deposition rate of material.
An optic device for transmitting photons, comprising at least three conformal solid phase layers, wherein interfaces between said solid phase layers are gapless and wherein said at least three conformal solid phase layers include at least two photon redirection regions for redirecting and transmitting the photons through total internal reflection.
An optic device for redirecting, through total internal reflection, photons having an energy above one keV, comprising a first solid phase layer having a first index of refraction and a second solid phase layer having a second index of refraction.
A system for focusing photons, comprising:
