Paper Abstract

The process of accommodating extreme measurement geometries, including aspheric cylindrical surfaces, is considered, and an absolute calibration technique for linear surfaces capable of 0.0067 wavelength (42 A) p-p with a precision (1-sigma) of 0.0008 wavelength 5 A is described. The technique was used to measure the absolute axial sag on the inside of a X-ray telescope.
