Mirrors For X-ray Optics
The mirrors can be made of ceramic or metal foil. The most commonly used glancing or grazing angle incidence materials for X-ray mirrors are gold and iridium. Even with these the critical reflection angle is energy dependent. For gold at 1 keV, the critical reflection angle is 3.72 degrees.
The utilization of X-ray mirrors simultaneously requires
- the ability to determine the location of the arrival of an X-ray photon in two dimensions and
- a reasonable detection efficiency.

Famous quotes containing the word mirrors:
“Poets are the hierophants of an unapprehended inspiration; the mirrors of the gigantic shadows which futurity casts upon the present; the words which express what they understand not; the trumpets which sing to battle and feel not what they inspire; the influence which is moved not, but moves. Poets are the unacknowledged legislators of the world.”
—Percy Bysshe Shelley (1792–1822)
