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:
“Our age is very cheap and intelligible. Unroof any house, and you shall find it. The well-being consists in having a sufficiency of coffee and toast, with a daily newspaper; a well glazed parlor, with marbles, mirrors and centre-table; and the excitement of a few parties and a few rides in a year.”
—Ralph Waldo Emerson (1803–1882)
